Ask yourself. What is it that you really want?. Whatever it is that holds you back right this moment, are going to do the same thing tomorrow and the following day to if you don't act now. I am not telling you to quit whatever you are doing, but you owe it to yourself to at least see if that dream of yours can become more then just a dream.
Maybe you love what you do and if so I am more then happy for you, but if you don't and keep doing it because it's all that you know, or you have been there for 20-30 years and just waiting for retirement, then that is you whom I am talking to. Surf around and see, maybe you get that jump start that finally get's you to were you wanna be.
