I'm a college student and I'm also working as a software engineer.I'm somewhat close to being as occupied as you are. I'm also working on a side project while at home. I think the key to managing my life is prioritizing. You have to get good at prioritizing stuff when you are living a busy life. And the better you prioritize the better output you get.Also try not to get burn'd out while you are doing all of the stuff you do and don't forget to go to the gym and just wreck yourself there(read stay fit). Also try to sleep well. There's no general formula, just survive and win. About the work : I'm in the opposite situation where my work requires me to be constantly focused and come up with solutions, and my tactics are : give it all you got.
