All I can say is, sure follow your dream etc etc but if you have kids, make sure the wife and kids are aware (as much as they can be) of what your new career entails. I have two kids, thank God for his blessings and my wife's (due to our financial situation) not having to work, she is stay at home, full time, soccer mom, bakes cupcakes with them, takes them to school, etc, my kids are awesome little guys. Top grades, well behaved, dad comes home and they want to hang out with dad. BUT ! We have ONE chance to raise kids once they are born. ONE. 18 years and in reality only 12, as age 1 month thru 12 is when you really "program them" and 12, 13, and later, whatever happened before 13, they are retaining it. Just my opinion. And your kids are forever, a job is not.
Like someone said, You don't want to end up a bitter old man wondering, "what if?".
For what its worth bro...
