How do you get over the fear of doing a no-hand back flip?

Can you do the back flip first of all?? If you can then you shouldn't be afraid to do them. I taught myself how to do a back flip. I guess i just had a lot of bravery and courage.

If you are scared of doing the back flip on hard ground then....

I taught myself on the trampoline. Then i started doing it on my mattress. I had this really soft but firm carpet and i covered it with pillows. After i grew confident i took all the pillows off and started doing it on the plain carpet. Then after i got the courage i just started doing it on the ground.
