Starting something at 19 is risky. So is waiting until you have a mortgage to try.

Risk usually gets counted only on the side where you might visibly lose something. Waiting carries a cost too, and it grows, because responsibilities stack up and the amount you can afford to gamble shrinks. Nineteen is the point in your life when failure is cheapest, even though it does not feel that way from inside it.

Ask what trying would cost you right now, in specific terms. Compare it honestly against what the same attempt would cost in fifteen years. Then decide knowing both numbers rather than one.
