I’ll reiterate the “have fun!” advice from above.
Along those same lines, if you’re getting frustrated because you can’t seem to hit a certain trick, go back to a couple of your tried-and-true tricks, the ones you can hit every time. Play those for a few minutes, get your confidence back up, and then try your new trick again. Frustration is your enemy!
Also, know that you’re not usually going to hit a new trick on the first, second, or even third try. Some of those whips and suicides will take you 50+ throws to hit. Don’t be discouraged! You’ll be amazed at how consistent you get over time.
Oh, and have fun!
