Most won’t be able to hike full-time forever. If you are technically oriented and flexible, a crazy alternative is to move to Ridgecrest, CA, to work at China Lake as either a Government employee or contractor. Both are hiring.
1 1/2 hous from the Sierra Sequoia / Kings Canyon trailheads; 1 hour from Death Valley. Go back in every weekend - and every vacation period.
Not thru hiling, but 2-week wilderness treks help.
