My dad taught me that there are no limits

My dad taught me that there are no limits and that I can do anything and be anyone.
When I was a kid, me and my dad would design safer planes, talked about flying trains. And that there are no wrong questions.
I was always a curious kid, I would ask him too many questions and he seemed to know all the answers. He would say that he was a fountain of knowledge. That he had read huge number of books. That helped because then I could ask him any question. There was no restraints on my imagination.
This was before google and before I got access to internet. He was not always right. No one is including myself, like for instance he would say there are 6 groups of salts. And he was extremely proud of himself for memorising them. When I went to high school I found there are 6 groups of basic radical and 3 groups of acidic radicals that we have in salt detection. Thanks to him forgetting this fact, I never did even after 16 years.
I must say that he was rightly proud of memorising the detection formulae. Memorising them was a nightmare.
