Should i quit skateboarding?

hi ive been skating for around 4 months now. i can ollie and manual. i try and learn how to heelflip but when i heelflip the board flips its just that i cant land on it. i also try and pop-shuvit but my board doesnt rotate for sumreason. i mean do i suck too much to skate? i love skateboarding alot and do i need actual skating lessons
