I've read all the self-help books about habit creation, procrastination, and mindfulness. If you haven't, you don't need to. Here's the only thing I'd care to share: the 5 minutes rule. It comes from Kevin Systrom, CEO of Instagram. But it's not a novel idea.
5 minutes is usually what it takes to go from dreading doing something to loving doing it.
I use that in meetings. I'm an introvert so I don't love meeting new people. I always make a deal with myself that in 5 minutes I'll feel cool about it.
I use that in presentations. Again, I don't love to speak out loud in front of people. But after 5 minutes, I get caught in the game and start to enjoy it.
I use that for deep work. When I have a big research/writing project to do, I open a Google Doc and try to put a few things in there to get the engine going. After that, the inertia keeps me going. Inertia is useful and works for you.
This works well for daily tasks. But I don't think it applies well to bigger things in life. I think there should be a 5-week rule for new relationships, a 5-month rule for new jobs and a 5-year rule for tougher, longer-term projects. Start by doing it, and re-assess if you still dread it after that. You might catch yourself liking weird-tough stuff such as going to school, working, exercising or practicing piano.
p.s. the 5 minutes rule is the only way I can write these blog posts every day!
