Notes are good. Notes help us remember things; notes help us crystallize our thoughts; notes help us keep things together.
Together with To-Do Lists, these two simple tools are among the best practices for keeping things together, progressing, going forward to accomplish tasks, projects, goals.
Paper form or digital? Whatever works for you, whatever is easiest, whatever most practical to maintain. Do what works for you.
But DO. Notes to self. To-Do Lists.
