Kwaku take advantage of the advice he gave you. You can enrol in school (adult education) at this stage and upgrade. It will help you because you are still young!
One of the painful experiences life has taught me is being Ungrateful.. It really hurts when you help someone who is down to rise up and stands firm on his feet To insult and disrespect you when you ask the person to help you climb up. They even tell you "Entitlement". Hmmmmmm.
