It is recommended that you schedule as many of your activities as possible as the first type. Especially when you want to establish a new habit, such as going to the gym. If you schedule a fixed time, there is less friction to decide each time when to go, i.e. moving the decision from system2 to system1.
Set a time once per week with a friend, to do weekly planning. In the meeting, you can go over your Life Quest Dashboard to see your status in the game, and then decide what steps you want to take in the coming week, and when to schedule those steps, to make sure they happen.
