I'm not going to be the feel good guy for you. I think you should work for someone else for a while. You have no clue what you are getting into. Keeping all the change statement and the thought that you can get all those other comm'l jobs all of a sudden means you really don't have a good grasp on what is going on.
Your dad would be neglecting his duty to his company if he just gave you this work without having any experience.
So unlike others making you feel good, I will give it to you straight. This is more than I believe you think.
