I like to separate out projects from tasks. For me, project is something that requires multiple tasks to complete. I have Trello boards for tracking projects in various areas of life. I will only put tasks in todo list for projects that I'm doing. I will keep checklist of tasks that need to be done for each projects if want to work out in advance.

This system is great for tracking house projects since there is always a large number of them. It is also good for planning things for the future, I have lists of plants to get in the fall.

The problem I have with this system is that I have enough regular tasks that don't pick up many projects. I also don't run the process for syncing tasks frequently enough. I wish they were all in one system.
