So it takes longer to go through school, if it is what I want to do, I work on it as long as I need to. Not anything anyone can do anything about whether you are fine or not? Do the best you can with what you have and work on what you want to learn. We are all different and have different attributes, abilities, resources. Maybe you are trying to learn in a way that is difficult for you.

Do you know about learning styles?
