Skate with people better than you for sure.
Also just know that for most tricks you can do them but you have to try it as if you've done its 100 times before. If you can kick flip and back 50, you just can do a. kick flip back 50. Whether or not you are in the right headspace to commit 100 percent and land it is another thing but the knowledge that there's no reason I can't do something helps.
