Try not to think about that too much, you can't change the past and you only have the present. Once you realize that you can start enjoying the present moment doing whatever you like and can. If you start coding everyday now in a few years these worries will seem silly to you and you will have new worries to think about. In the end it doesn't matter, whether you are the most productive person even or a drunk homeless outcast, your time will run out one day and you will be gone. If you can accept this you can free yourself of regrets.
