Provided I'm still in the line of work that I'm in (Construction/Heavy Machinery) The best I could hope is to live to 65 and then have enough money to cash out in some sense. Preferably with kids/fam/wife but if not, fukk it, I should have something to live on by then and quit, 'cause I've seen too many "old" guys in my field, huffing and puffing after fukking up good money they should have retired with.
