Just think about your typical polymath like da Vinci. Sometimes people can be really good at many things, and if they assume that they can only be really good at one thing, they may not even try to be really good at many things. So my main point is: don't assume from the beginning that you can't do many things well, or it will be a self-fulfilling prophecy.
