That is very much a legitimate concern. I know people who have ended up in that position, one of whom posts here and, I beleive, is now on his way up with a flying job, and others who have lost their marriage because of the strains of becomig a pilot. However there is work out there if you are willing and able to take those risks and to work hard, accept a drop in living standards, accept that your early jobs will be paid less than what you are on now. I am afraid that it is a risk, but everyone I know who has the time available (i.e. is not starting on the older end, where time is more critical) and persists seems to get there in the end.
