It takes a lot of time and hard work to make friends on the platform. When I started on Steem / Steemit I wasn't an outstanding writer but from practice I've improved my skills in this field a lot. Becoming a dolphin is very challenging without first investing a little into SP. Because SP is a useful tool for networking it can help you make friends... I vote posts I like and comments that I like. Sometimes you can make friends this way. Keep learning and trying your best and keep experimenting. If you can't become a dolphin right away don't feel bad, just be a life long learner and constantly strive to improve your skills and build new ones. Good luck!
