King of a puddle or just another fish in a big sea?
Expand your horizons, play more different players.
I used to play lots with a No.2 for a Div111 school. He'd beat me mostly 4's and 2's, and in the last 30 sets, every single time. He was also my doubles partner.
When we played tournaments, I'd usually go deeper than him. In doubles, he'd hold me up, me failing every single match.
I quit tennis for motocross, he got better and eventually became a solid A raked NorCal player.
Expand your horizons, but don't forget your roots.
