Unburden your mind through Bullet Journalling

Create the four core Collections
Those are the Daily Log (daily tasks, events, and notes), the Monthly Log (set tasks and events in the current month) the Future Log (planned tasks and events for a more distant future), and the Index (timetable and a map legend for the log, with page numbers and symbols)

Create other relevant Collections
Those Collections can be the Goals Collection (short and long-term goals), the Gratitude Collection (things you are grateful for), etc.
