I tink u worry too much. Be like Nike - just do it. U can try to be no 2 shooter at friend or relative wedding mah. Then stare hard hard at the person who is main shooter see how the horse run. I tink if u wait for master to come find u to teach u is wait long long long. Now no master want to teach for free, teach for money got .
Your lens already better than most people - 17to55 more than enough to do wedding - if people can use kit lens 17-70 to do wedding 17-55 sure can one. All about how u use sword - precious sword with lousy swordsman is a good as rotten metal. Rotten metal in hand of good swordsman can be precious sword.
A good master will only teach if teach u, he also do something for himself. even if make himself happy also doing something for himself. teaching u to make u happy do nothing for master. so understand how to make teaching u good for master then can find master. problem if u too bad master must spend much effort to make you into bird that can fly - why he want to do that ?
short not problem - house always got chair. chair u can stand on or make people sit in so now they not so tall ehhh. or u can do up nose style of photo - different if can make nice nice then call it ma style mah.
english good no good no problem - problem only if u say up they go round and round and still catch no ball. if that bad practice speaking more.
u want to go some where be some one - must start walking to find way - not wait for mater to come find u. start doing if u do right, then when time ripe master will come. whether if teaching for free or teaching u pay for not important - teaching never free even when u no pay money always got costs. life no freebie what u get u pay for some where some how.
