how do you be like someone else

 You can't think your way into feeling different. You can only change how you feel by actions.

I think that's true. And I think if you want to be different or be like someone else I think you have to do the things they do, the way they do them. For the most part I think what anyone tells you or whatever you end up hearing is mostly useless if you don't end up changing your routine and what your body is physically doing. 

By the same token, if you're in a system that tells you where to be and when, like a job or a school, that's going to have a direct effect on who you are. It's going to mold you. And none of that is accidental. What you're supposed to be when you are in those spaces and doing your tasks is all serving a well-defined end.

It's why I don't put much stock in the idea that you can place yourself within a system and subvert it. You can't rely too much on this idea that there's an inner you that exists independent of everything you're doing and everything going on around you. Actions have outcomes, no matter how mundane, and you are what you do.
