One of these is likely to be true for you. Maybe more than one.
You don’t know what to do, at least some part of it.
You know what to do, but you don’t know what will happen if you do it.
You know what to do and you know what will happen, but you don’t want that to happen.
If any of these resonate with you, then that might give a clue about what to try next.
In addition, you can act without feeling motivated. Some people like starting with 10 minutes of effort or a single step, because sometimes doing anything is enough to sustain energy and focus. It’s a way of using inertia to work for you, rather than against you.
