It takes 30 days to form a new habit. You just have to get there. Routine is the key. And early mornings are the best, because you never have the excuse to say "I've had a shitty day at work, all I want is a pizza and a beer". For me it was the gym. Every morning (almost!) I roll in there at 6am before I'm even really awake. "Alright, lads" I say, "alright", they reply, it's always the same crowd, they are very serio…
I bet there's a ton of joggers who don't feel like going out when it's -5C and there's the first sign of snow on the pavement, but they put on their tracksuit and go.
I'm a writer. I sit down at my desk in front of my laptop, turn on the lamp, feed Curly, Hugs and Kisses (my three goldfish who would get multiple daily feeding's if I didn't drop this step after the morning) open my laptop, plug in a pair of noise-cancelling headphones, set itunes playing and open my word processor. I quickly start writing where I left off. I don't even need the steps any more, I just sit down and write.
I have a pair of track pants (the disgusting ones with a plasticy outside) that when I put on I'll paint any room you put me in. I painted a room that was 40ftx40ft and then painted the ceiling. These became work pants unconsciously, they were just a crap pair of pants I didn't care about ruining, now they're a uniform.
They teach these kinds of cues in psychology for people with anxiety disorders. That when you pull on your right ear lobe you associate it with a happy memory, eventually you'll trigger the happiness when you do the action. This is what most children do by accident, they have a blanket or toy that soothes them and can be used to keep them calm.
Habits and routines are very powerful if you learn how to use them, but it's best not to rely on them or you can cause other problems (hence why children shouldn't be allowed to keep a blankey too long, or they'll develop a psychological dependence more powerful than cigarettes).
