Thats not what I meant - the OP stated "I dont have kids and I want to be able to work overtime and focus on a project" -- so, my comment was "well if you dont have kids, you should be better able to work overtime and focus on a project"
> I <...> would like to be able to not be stressed and work overtime and solve hard technical problems and move towards a more rewarding job
I cannot tell whether he is saying he would like to be able to work overtime, or whether he doesn't want to <be stressed and> work overtime. I would assume, "work overtime" has a tighter coupling with the preceding "not" than with the preceding "would like to", but can't tell for sure.
