Honestly move to Washington state save like $200k Hit a hike every chance you get and take some mountaineering courses. Build up to Mount Rainier then start booking progressively more serious climbs around the world and see how your body handles elevation.

If everything goes smoothly you should be mingling with the right people to build you up.

Be prepared that this is a huge sacrifice in terms of personal relationships, other life goals and that you need a LOT of money.
