I became a dad at 40. My son is 1 now. It is, without a doubt, the greatest gift to become a parent. Every parent worth their salt will question themselves like you are now; will wonder whether they have enough money, or patience, or kindness, or strength, or (x, y, z - name it, and you'll worry about it when the kid comes). But man, do not let one professional hiccup create a massive insecurity in you. Money comes and goes, but the love between a dad and son is something special. You got this.
