KEEP AT IT!!I was just like you-Landings just seemed to go tits whatever i did.Had more bounces,crap flares & go arounds than I could ever count.But one day it IS going to work out & when it does,it'll stay with you!It's very easy not to study when you feel so low on confidence,but now is the time!Get the books out & go for it-knowledge itself is a great confidence builder.Have you talked to your instructor about it ?If (s)he isn't supportive then get rid!oh,and at 23 hours you're about the same as most people I know of.You're doing fine.Go get it!!
