I too am fairly new to cycling, and ride both Mtb's and road for about 20 months now. While I have made good progress, more than a few people have offered some great advice to me, and that was "it never gets easier, you just go faster", so with that said.....ride to meet your needs, and your needs only.
Ride the bike as often, far and hard as you'd like. The results are sure to follow!
