This sounds super simple, but something that helps me stay on top of everything is super detailed to do lists. I do this using One Note, but there’s tons of apps (bonus if you can access on your computer and phone, like slack). 

This helps me by writing down something I need to remember or something I need to do later, and would otherwise forget. This also helps me start my day as I can quickly remember exactly where I left off and what I need to do next!
