Exhaust the feedback process

What Alex said is paramount: specific feedback and trust.

Besides that, you want to run a while(1) loop with

1. Seek feedback
2. Work on it
3. Communicate back success or dead-end/challenge and asking for more

on a regular cadence (ideally weekly). You might get stuck on either parts: if you seek feedback, people might not give you real feedback easily, if you want to work on it, feedback might not be actionable (what do you do for the feedback like: you don't take ownership e.g.), and it is hard to communicate small wins or failures and ask for more -- what if they cover you neck-deep in the feedback. All these concerns are valid, and you want to dissect what comes up along the way.
