What next???

Hey im 18 and i got my surfboard - a 7'6 minimal and have been surfing quite a lot recently. I can stand up pretty quickly and ride up the beach. I never really fall off now which is gd
But what would be the next step? Would I try to trim the waves or maybe go out deeper cos at the minute im still able to touch down?I also find it kinda hard to paddle out and it takes ages. Any advice would be great! Thanx
