I did a lot of it in my 40s, sometimes driving interstate for a job and having to borrow a couple thousand from parents after running things too close to wire. 

they always got it back and I always paid my bills. Didnt really do much different to what do at home when there, just different attitudes at work, different bosses, different scenery.

Guess my health was better and I knew I would get work, getting too old now lol @Adge  had no fear then compared to now lol
