In the context of programming, every time I don't feel like writing code, I just tell myself: I'm not gonna write code, I'll just run the test suite and then come back to it later.

That causes me to open my terminal, which then requires me to getting the updates from upstream before running the tests, and then I have to inspect the new changes which then requires me navigating to the project..

By then, I'm writing code. This works really well!

For other things such as exercising, I just tell myself, I'm not gonna exercise, I'll just put on my headphones to listen to my "exercise" playlist. This causes me to walk to my bedroom to grab my earphones (I have a wireless one for exercising and always keep them near my workout clothes), which causes me to open the drawers, and by then, I might as wear change and then I'm all set!
