Be aware, it is more likely than unlikely that the cancer of GA will slowly suck the goodness from your being and as a consequence your passion to be an airborne machine operator will diminish. Life in GA is not for those who want a journey to somewhere decent (as you said you don't see hoards of older pilots in the GA environment)
That said, at your age, if you can survive and progress past the sewer pit end of the GA industry, there are still a few options outside of the airlines when you can have a semi decent existence e.g. (air ambulance, government/police air wing, RFDS)
