To be certain or uncertain that is the question?

One of the best quotes I have ever heard is THE QUALITY OF YOUR LIFE WILL ALWAYS DEPEND ON THE AMOUNT OF UNCERTAINTY THAT YOU CAN HANDLE TONY ROBBINS 1998 If you really think about this for a few minutes it will begin to make sense. A great example is if you know that you need 200.00 per week to pay your bills and you have a job that pays 300.00 a week you may be satisfied. If a sales job comes along that pays on commission you could make 1000.00 per week but on a week with no sales you may make 0 dollars per week if certainty is important to you the 300.00 a week job may be the one you keep.If you can live with some risk then you make take the sales job. Which one would you take?
