I think that it is important to find a balance. A person learns everyday without even being aware of it, but if someone is too focused on one thing then it is likely thet they will miss out on all the other experiences and learning opportunities. I believe that knowledge is among the most important things, but not only knowledge, also variety in knowledge. When you meet a person who knows everything about somthing, it can be interesting, but a truely wise personcan teach you many things.
