Daily: Reference my weekly goals and decide what I intend to do for the day. Look back on the previous day and pull over not-done items that I still need to do. It's very tactical execution. Examples are cleaning the house, finishing up taxes, or scheduling lunch with a friend.
Weekly: I write a summary of the areas in life I care about (work, family, social interactions, fitness, reading, volunteering) because my memory isn't great. I also reflect on the previous week's goals. Then I decide on goals for the next week. It's similar to iteration retro/planning at work. The big thing to watch for is intentions that show up multiple days but I don't end up executing. This is a sign that either I need to focus on it more, or stop wasting energy on it if it's not actually important. Examples of weekly goals are getting 7 hours of sleep, going to the gym 3 times, or building a feature in a side project.
Quarterly, or whenever I finish a big goal: Review the big picture goals. Are they the right goals? Are my weekly goals helping me achieve them? Examples of these are training for and running a 15k, completing a side project, or starting a band.
