Plumbing and heating bus. is slow as are many other trades, at least around the lake. It helps to have a few irons in the fire..Ive done ok lately day trading.
Pushups? You need to play along on the job.. check the oil on the truck or wipe off the hose etc but just make it look like your focused on work. If you were working for me and doing pushups id have to think how much time you are wasting during the day with non work related activities.. fired? probably not but you would be talked too about the whole "being at work" thing.
