loiter outside office building in ya day off causal clothes to mock the office drones. the more "i ain't got a thing to do" about it the better.
take advantage of the time off to hit up places usually totally packed on the weekend. movies. museums. local attractions. the downtown if your town has one.
Taking advantage of "off peak" venues is a really good idea. Do some research of the area you currently reside in. Look into some places you can tour/see/view/explore on your own during these times. Take your camera along and use the adventure as an outlet for expressing your creative side.
Occupy your time constructively until real changes start taking place.
I say: when you are ready the "how to" will show up. I have found that life has a way of preparing you for better during these times.
Be fearless, it is not always an easy thing leaving your usual routine behind. When all is said and done, when you have moved the mountain, changed your life for the better
YOU evolve and grow as a result.
Take up the challenge and be creative have
FUN! Good luck!
