I get it, you dont know what to do. You want to change career but really haven't got a clue where to start .
A little advice - purposely fail :)
1) Try something - anything!!!
2) get it wrong!
3) get feedback / take learnings
4) refine how you do things based on feedback or learnings
It can be something super small like picking up the phone, sending a email, speaking to a friend. Use the learnings to create new thought processes and actions. If something doesn't work, analyse why, spend some time thinking about this and do it differently next time.
Get off the hamster wheel!
The scariest thing about failure is the thought of it, not living it
