be able to do both, but at my age and income and all that - I'd stick w/your current job. The one issue I agree with is personal growth, that is compelling. But I'm telling you time with your kids is more important. And don't forget your wife, obviously.
I will say that it's important that kids see their dad working too.
Good luck, the money is great as long as it doesn't require sacrificing your ability to spend important time with your wife and kids. The best part of your life is that you have a small part in their lives.
