Starting something new is hard. You never know how to go about it and so you need to fumble around and focus and think about what you’re doing. Starting something new is also usually exciting and so you’re willing to put in all that effort. Deciding whether or not to stick with it is usually the problem. Decisions are complex things and they take time and effort. Often enough, most of my free time is spent in deciding what to do with my free time.
If I write something everyday, somewhere down the line I won’t waste time deciding if I want to write. I’ll open up my laptop and write just as naturally as I turn on the TV. I don’t think it’ll take more than a month. Eventually, I’ll write when I’m tired, I’ll write when I’m drunk, I’ll write when I’m hungover and I’ll write first thing in the morning when I usually have nothing to say. I won’t think that I can sleep and write when I’m well rested tomorrow. I won’t worry that my writing wont be coherent when I’m drunk. It won’t hurt my head to put sentences together when I’m hungover.
I’m not saying that what I write will be good, but it’ll be different. Think about it, if I only write when I’m enthusiastic and well rested and ready to take on something new then all my writing is going to eventually sound the same. And this isn’t true just for writing, it’s for anything I try to make as a hobby. Work remains an exception because it’s a habit by default. But everything else I make will tend to be so one dimensional unless I do it when I usually wouldn’t be doing it.
And that’s why you do the things you want to get good at everyday until you don’t need to make a conscious decision to do them anymore. That’s the importance of habit.
