In prayer, ask God what path you should take in fulfilling your passion; learn to hear His still quiet voice; He will answer you.1
Confirm what you believe God is saying to you. What do others think about your decision (especially those who know you and have Godly wisdom?)
What does the Bible say? Is there anything in the Bible that would say not to?
Circumstances have a lot to do with it. Is it possible? Well, with God anything's possible; as long as you're willing to do it His way.
Are you willing to do what it takes to be successful God's way? I hope so! If not, and you start down the wrong path, then it's going to be a long path.
If everything seems to be in agreement, "Go for it!" There's a good chance you're on the right path. Just remember who you are, however (a Christian); live and act accordingly. In the end, you'll have run a good race; a path which was pleasing to God, to you and to others. That's more important than doing whatever it takes to make the most money (no matter what.) Do it God's way.
God bless you and remember, God first, your family second, and everything else after that. That's your priority.
1 (James 1:5-8)
