Depends on what your dream is, if you want to be a doctor or a lawyer you should defenitely follow that. If you want to be famous its a huge gamble depending on luck more than anything so I would not advice it.
I don't think so. Anything that requires a high level of skill can't be done by just anybody. Even something like carpentry requires you to be handy. Not everything can be learned even if you put a lot of effort into it.
