i do my own stunts - You do everything yourself because other people are too weak

You do everything yourself because other people are too weak or too slow to help you.

I did my own stunts because the guy who was helping me took five minutes to do a simple fall.

I did my own stunts because the other guy tried to do a backflip and landed on his head.

I did my own stunts because the person who was supposed to help me had no idea what a stunt was.
