Hi Garry,
Welcome to the world of the free!
It didn't have to be window cleaning, you've just had your wake-up call that working for a boss is a waste of your time and talents. Especially being a wage roll number in a massive operation like the Post Office.
But what happens when you've grown enough to need an employee? Then you'll be a boss yourself! I'll leave you to answer that one all by yourself.
Congratulations chum, and I hope to see lots more of you on these boards.
All the best, have fun, and don't forget that "Freedom Moment" when your overalls are soaked up to the knees, you're a couple of days behind with the work, and one of the boys is off on holiday (paid!). Ain't it great!!
