You have to step up and confront your fears. do shit that you normally cant summon the courage to do.

There is no easy answer. You just gotta nut up.

There is a saying that a hero is a coward in a corner. Put yourself in that corner.

Try to find your fear. No matter how ugly it is, your fear is also a part of you. Accept and make a peace with it, then proceed to take a one step forward despite knowing it exists.

For your ambitions, like other has said, put yourself in the corner. Think hard and desparately about your ambitions, think about how very important they are to you and you're one step to losing them.
Make it your mindset that your ambition is always one-step away to be lost forever, so it could fuel you into action where you'd rather trying and fail than being coward who prefered to stand wathcing them lost.
