    7. SHARE I’ve read all the articles and listened to all the podcasts about procrastination. I’ve tried all the tricks—including literally trying to trick myself.Sometimes hacks work. Sometimes an article about how bad a habit procrastination is will kick me into gear and help me get things done early for a change.But it never lasts. I’ve never fully kicked procrastination to the curb. Even when I’m on a productive bent, I’m still a procrastinator at heart.When I’d just about given up on ever curing my bad habit, I came across a theory of procrastination I’d never heard of, and it completely changed the way I think about procrastination.The truth is, procrastination is more about our emotions than our tendencies for laziness or just being “bad at deadlines”.  At its core, we procrastinate to keep ourselves happy in the moment —which makes complete sense, right? That is, until we’re pulling an all-nighter to meet that client deadline we had weeks to prepare for.Understanding why we procrastinate allows us to develop effective strategies for getting started on our important projects now, rather than waiting for tomorrow. Here’s what I’ve discovered in my own journey to stop putting things off for later, and the concrete steps I’ve found along the way to address the root cause of my procrastination.Why we procrastinateProcrastination is thought to come from an emotional reaction to whatever it is you’re avoiding. Researchers call this phenomenon “mood repair”, where we avoid the uncomfortable feelings associated with our work by spending time on mood-enhancing activities, like playing games.As Timothy Pychyl, an associate professor of psychology at Carleton University, explained it “putting off the task at hand is an effective way of regulating this mood. Avoid the task, avoid the bad mood.”Of course, the mood lift is inevitably short-term. Studies of college students have found the habit of putting things off only increases negative feelings later on. While procrastinators tended to be less stressed and healthier in the first school term, by the second term these results were actually reversed.This brings us to the second key insight into why we procrastinate: research shows that our brains are actually wired to think about about our present and future selves as two separate people. That’s why we’re able to prioritize our present mood at the expense of our future well-being even though it’s an irrational choice in the long-term.A study run by UCLA psychologist Hal Herschel and a team at Stanford University found that participants actually engaged different areas of the brain when they thought about their present selves versus their future selves. In fact, when people were told to think about themselves in ten years, their brain patterns closely resembled  those observed when they were asked to think about celebrities they didn’t know.This separation of present and future self encourages us to make different decisions about ourselves now and in the future. For instance, one study showed people asked to tutor other students would offer to do so less in the present, but would offer more of their time in the future. To sum up the research, we procrastinate because our brains are wired to care more about our present comfort than our future happiness.So what can we do about it?How to overcome your procrastination habitBased on the research, it’s clear that we have two ways of dealing with our procrastination:Make whatever we’re procrastinating on feel less uncomfortable, andConvince our present selves into caring about our future selves. Here are 8 concrete strategies you can start using today to address the root cause of your procrastination…1. Make getting started ridiculously easyTo overcome our psychological aversion to uncomfortable tasks, Dr Pychyl suggests “[making] the threshold for getting started quite low” and just getting started. Often starting a task is the biggest hurdle.For example, Dr. Pychyl says “A real mood boost comes from doing what we intend to do—the things that are important to us”. Knowing this, we can reason that although getting started might feel uncomfortable, we’re likely to feel much better once the task is done. Compare the mood boost of having done what you intended to do, to the disappointment and frustration of dealing with the consequences of procrastination later.In fact, research shows that progress—no matter how small—can be a huge motivator to help us keep going.My favorite trick for getting into a task I’m dreading, is to start with the mindset. I start by just thinking about the task for a while, until I’m drawn in and can’t help working on it.If it’s a writing task, I might pull up the draft I need to edit and just sit and read over it. Soon I’ll find myself changing a word here and there, or fixing typos. Then I’ll think of a whole sentence I want to add. And suddenly I’m well into the task, without really pushing myself to do so.If it’s coding I need to work on, I do a similar thing. I open the project in Xcode and just look at it for a while. My brain starts to get into the coding mindset as I read over what I’ve written before. I ease myself into the right mindset for this project just by gently immersing myself in it at first. Then I might remove or add a comment, or make a small change to the code. And before I know it I’m stuck into the work I need to get done.Poet and author Mark McGuinness used this method to write a book:A few months ago I just created a file in my book writing software and laid out the chapter headings, and just started playing around and rearranging them. And each time an idea came to me during the day, I just added a quick note inside each chapter. Recently I’ve been opening up the doc in the mornings, just looking at the table of contents, and just adding a few more notes here and there. It’s a slow ramp up where I just tell myself to add a few things here and there, no pressure.When McGuinness wrote that paragraph, he’d already written 12,000 words of his book. “I haven’t really started writing it yet,” he said. “And since I’ve not been officially working on the book, resistance and procrastination hasn’t shown up for work either. It’s been fun.”If it helps, you can also try using a timer for this approach. Set the timer for just 5 or 10 minutes. While the timer’s running, you don’t have to work, but you can’t do anything else. You have to sit with your work, even if you don’t get started. Personally, I’d rather work than do nothing at all, so I wouldn’t even last five minutes before this trick made me get started.2. Do the right thing for the wrong reason
