1.) Make sure there’s no tension the string, much more in learning whips/slacks/suicide tricks because a good tension has a good outcomes. 
2.) Practice the trick in a good mindset.
Because If you practice with a crazy mood and you can’t do a trick successfully then you’ll throw the yo-yo & tah-dah! stripped axle/bent/ding/scratch/vibe/wobble or even total broken yo-yo is the result.
3.) If you’re learning “motion tricks” like Ninja Vanish, Trapeze Triangle Slack or wierd tricks like Magic Drop or Pop tricks like Spirit Bomb and Kwyjibo, use only one reference. because the tendency is you’ll gonna be confused. (You know what I mean?)
And watch tricks that are “slow-mo’ed” video’s by Brett a.k.a Ibanezcollector/raytsh/Xdohls a.k.a Jeremy Levine/Grawrd a.k.a Gerard Armento for good explanation and HQ video’s.
4.) Don’t rush and post a thread just because of you’re stuck up in a trick. If you’re really had a problem that really need to be clear/answer then that’s it.
So what I mean is try it yourself, watch the video a couple of times then stand up & throw.
5.) Please use the search button. If you can’t find what you’re looking for, then that’s the time that you need to post.
I know that we have different skills or whatever that is bugging you when mastering/practice something (I mean Talented :D). Just relax, don’t be sad if you’re still in that beginner/intermediate trick somehow your now a in a month throwing.
Watch Freestyles by your Favorite Players, get inspired or watch videos that you have (kinda or exactly) the same style like yours.
That’s just my tips okay? And I don’t care if this thread would be sticky. It just a matter of how my e-mails are spammed that the title is “how to be good like you”. Hey pro’s, do we have the same problem? 
Or if this thread would be stick’d, why not?
