When I work my side project I keep all ideas and tasks scribbled randomly on a page in a notebook. If I try to organize those pages or keep tasks away from ideas on a different page I just crash. I have to be sure not to try to organize any of it. I barely use the lines and just cram in little blocks of text wherever I feel they should go in the monlment. I flip back through the pages and have a record of what needs done, what I have done, and the things I need to do or think I need to do. This somehow enables me to chew through a tremendous amount of work compared to projects at work that are rigidly organized. Sometimes I will write down a huge list of tasks, never look at them again, work for a few hours, and check my notes to find that I can cross them all off. I have tried using the tools we typically use at work like Jira or Azure Boards. Total waste of time that stifles the mind.
