Many young people are unsure what they want to do for a career. Don't fret about that too much. I had no intention of becoming a lawyer but it eventually became clear to me that God intended that I become one. The financial means by which you will take care of yourself and your family are very much matters of God's providence. God knows that these things are important and gave us two very helpful directives when it comes to matters of money: "seek first the kingdom of God and His righteousness, and all these things shall be added to you" and "do not worry about tomorrow, for tomorrow will worry about its own things. Sufficient for the day is its own trouble." Pray and try not to worry about the future.
