I think everyone can get good at LD'ing with enough dedication and practide.
What you mentioned about trying to controll things but failing, because you knew you would fail is a common trap.... Because you are thinking its not going to work, it is not. If you want to summon something, think its going ot happen and it will... but if you're uncertain and thinking its not going to happen, it wont! Dreams are all based around what you think is going to happen next.
