You can have a belief, sure. Believe that you'll be a great wholesaler and you'll make a ton of money...but the thing about beliefs are, they're always challenged. You'll have this person telling you can't do something, and that person telling you how impossible what you're trying to do is—and eventually that belief you once had, starts to fade away. You start to question your own belief and wonder if it's worth believing. But once you throw a conviction in there—A REASON behind that belief...that drive and that fire will keep that belief concrete in your mind, then you WILL succeed!! The belief that holds conviction will come to fruition.
