No matter who has the job, an excess amount of work is there, don't let it get to you. There's a cut off time for a reason. You have to stop somewhere. Just stop. Take time to listen to your co workers when it matters. They matter too. As long as you aren't slacking off, be present with people when you can.
To invest in Apple, Facebook, buy a house on the Sunshine Coast, buy that condo even though your bf isn’t ready, btw dump that bf, stick to having the one kid and don’t marry that guy. Don’t put off travelling. Yes go to nursing school in your 20’s.
save and invest. look for long range value investments. start as early as you can with a much as you can, even if it seems like that's not very much money
A job is just a means to pay bills. Don't take it too seriously. They'll just use you. Take life one day at a time and mind your money. Pay off debt. Put your money in an index fund or ETF through a brokerage account. You'll do fine.
