Your post seriously made me smile. I'm a house flipper and I know the exact feeling your talking about with feeling like you want to give up in the first couple of days. The work can be difficult and frustrating but ALL OF THAT gets washed away as you see certain portions of the job become complete knowing that you worked your tail off to make it a reality. It's one of my absolute favorite feelings! What's even better is when its all completed and operational... going back and seeing it in use, the way it was intended. It's one of the most amazing feelings :) You'll love it!
