I think it's important to first assess what struggles you have with executive functioning and time management. What is the problem? Once you identify the problem (too many things to keep track of, needing a list app, post-it notes everywhere, communication, etc.), only then will you be able to look for solutions that will help you individually. And remember, individualism is really important. What works for one person's style and personality may not work at all for someone else who is completely different. Don't go completely against who you are. Honor that, acknowledge where you need improvement, and go from there.
