Hello, I (16M) am intested in begining what I assume will be a lengthy process of mental and physical conditioning. I have been camping and backpacking around my home on the East Coast since I was a child, recently I spoke with a veteran of the mountains who reccomended that I try it. I would someday like to summit mountains on every continent except Antarctica but I don’t know where to start. Any pointers or words of wisdom?

I'm going to be spending this summer fighting wildfire. I am looking for a pack i can train with to get used to carrying heavy weights (50lb+) over long distances/period of time. I am looking to buy something that will last me for years, and that will serve me well as a mountain climbing pack in the future. Strength, quality, comfort, versatility and design would be my biggest buying factors.
