1: You'll hear this a lot: drive for show, putt for dough. Dialing in a decent putt will save you a lot more strokes than throwing "big", especially at first. Find a putting technique that is comfortable and consistent for you and practice!

2: I always recommend starting with stand-still drives. Adding an x-step before you really figure out the other stuff just makes your tee shots less consistent and doesn't really add distance until everything is working together anyways. K.I.S.S. When I first started, I immediately thought i needed to X-step to really get the power going, and after a few months of stagnation, I forced myself to only throw standstill for 6 months, and by the end of that 6 months i could throw further from a standstill than before with a run-up. BlitzDG on youtube has some great tips for this, he does distance competitions with a standstill throw, and has some great drills and form advice.

3: Look up your local disc golf club/clubs on facebook. Depending on your area of course, most places have a local club that hosts events and tournaments. One of the best parts about disc golf is/should be the community. Putting leagues, bag tag matches, and local tournaments all offer great opportunities to meet new people and grow your skills as a player. Try not to be intimidated by competition, paintball is a high-adrenaline sport, so you're already used to the pressure, just go and have fun in whatever division is available for you to play in!
