I too am only 25 years old, and I've been wheeling for 2 or 3 years. The best advice I could give anyone is to start as small as possible and don't build your rig past your driving abilities. This is the worst mod you can do to your rig. If you don't know what your rig can do with the bare necessities, how can you wheel it properly all built up? I had a 90 xj that I could go anywhere in, almost, and now I have a 99 XJ Classic that holds up with most others running 33's or bigger. I have 2.5" lift and 30's, and I have a blast. Even though some of the advice you've gotten was maybe a bit harsh, you still need to listen to reason and be smart about your rig's mods. It all costs money, sometimes lots of money, so be smart, stay safe, and I would even suggest buying some cheap set of A/T's and wheel your rig stock for a month or two, just to see what kind of mods you absolutely have to make, not just ones that look cool. Good luck with the rig, Keep on Jeepin'
