If you have a dream, to make it happen, all you have to do is start with one video and take it one video at a time. It may seem a little daunting to go from registering your YouTube channel to making it a full-time career, but if that is an aspiration for you, it's 100% doable if you're authentic, if you're persistent, if you put your best foot forward, if you come at it with realistic and authentic aspirations and intentions. If you try, then it's possible.
