Perhaps they may work for you, too. You are kidding yourself if you think that repetitious, fortune cookie slogans will make a difference especially when you had a crummy day. C'mon, you're smarter than the gurus who sell this junk. The way to a great and positive attitude is to make the good stuff happen. You won't believe squat until you just do it.
Patience is a virtue.
Take it one day at a time. It sounds great except nothing ever gets accomplished. You get distracted, overwhelmed, sidetracked. You die broke and unfulfilled. Impatience is the best thing you can possess because it will make you get off your butt and do something today.
