As an adult you have to accept the good with the bad. The good is the opportunity to do you as well as you can the bad is there are no guarantees. My industry may be obsolete tomorrow and I have to plan for the eventuality and live my life accordingly. Bill Gates once was asked why he runs his business as if it were going to be gone tomorrow. He said, there will be a 16 year old kid with a better idea some day just like me.
Cold hard reality of capitalism.
