Heavy stuff.
Sorry to hear your Blues Newguy.
As Ted said, I think they say you are in the Top 5% if you have food in the fridge, money in your wallet, a roof over your head, etc...
My "Value Adding" advice... We all need to learn to say "No". Sometimes when there is too much work to do, you need to push back and say "No".
I am rarely asked to work weekends... Not much gets under my skin, but just the very thought of working at weekends gets under my skin, and the question, "can you work this weekend?"... well it makes my blood instantly boil. IT MAKES ME INSTANTLY IRATE !!

Thankfully though, I keep a "poker face", and instantly reply with, "sorry, I have a few things booked and paid, and we're actually going away for the weekend to ......". Even though I would blatantly LIE about it, there was NO GUILT on my end! I would also happily get about town, not caring if "the boss" spotted me. Who cares? 1:3000 chance of the boss running into you, especially if he is in the office!!

. In those days, you would have had to kick and scream for over-time pay, plus I didn't have any equity in the business, so there was almost zero point working on the weekends for "perfectionists"!

* I have gone through a period of working 2 jobs, working 7 days a week, but I was happy just raking the cash in at that point, plus my weekend shifts were 1pm-9pm working at a cruisey Petrol Station near the coast, as a Driveway Attendant, 75% female clientele (some in bikinis in Summer), as we were the last Driveway Service joint for miles around. So I could surf in the morning, and still go out on the town for a few hours on Saturday Night. Plus a few mates would drop into the servo for a chat... So in an 8 hour shift, I probably did about 4 hours work !!
