As shown very simply in Zootopia there are always people who try to hold you back and doubt you. The only people who can overcome those challenges are the ones who believe in their own abilities no matter what everyone else says. Such attitude and determination will sooner or later provide the individual with the opportunity he/she was looking for. Getting to this stage is the hard part, the rest is just taking full advantage of the situation. The short phrase that probably everyone keeps hearing is to never give up. Even though it may be exhausting to constantly hear those words, it is often true.
