First of all, I’m happy for your father.
However, trading is not suitable for everyone, and everyone can not be successful. In my opinion, if each person focuses on their own profession (even as a delivery guy), it's better than having millions of beginner traders.
Whatever you do, never be harsh on yourself or put your life through unnecessary hardship. If you're involved in any kind of exhausting work, stop it immediately because such work wastes the most precious thing in your life that is time. You might notice that when you engage in intense labor, your time passes so quickly that you can't realize it, and gradually your lifespan keeps decreasing.
"Stop it immediately?" I think you have no understanding of the lifestyle in African countries. For them, being unemployed for a single day means HUNGRY.
