Decision time.

On the 3rd I've got a decision to make. Do I or don't I want to resubscribe to chess.com? I haven't been a subscriber in a while and I'm starting to miss playing. I've joined a couple tournies and I'm doing the same as always. LOOSING!!! . Everyone tells me to stick with the game and I'll eventually get better. Is this really true? I'd hate to waste money if I'm not going to get any better. In the past I've made plans with a teacher but never did anything with him. I just didn't want to waste his time or mine. Ok I've made my decision I'll subscribe and do my best and try not to get frustrated and quit again.
