I was talking to a magician earlier today and he recommended that I major in what I like most, not about magic, so that I could have a career to fall back on. Would this work? The thing is that he did this but he never went full-time, so I don't know if it was reliable.
That is EXACTLY why it didn't work.

It is important that you get advice from people who are currently doing what you want to do. With the magician you talked with, if he isn't performing full-time, then how can he help you be a full time magician?
If you want to be a full time performer then you will realize that college isn't the way. Think about what college does...it helps you get a job. You take all these classes, you only remember 5% of what they taught, and then you go out to get a job.
As a full time performer, you're an entrepreneur. You have your own business. So you must learn how to discipline yourself with time management, you must learn marketing, sales, etc. Sure there are college classes on marketing 101 but I can guarantee you that they don't teach as much as you can get from a single book at the book store.
If you want to be a full time entertainer then you must become an entrepreneur. You will be working for yourself so you have to create your own daily schedule and each task you take must move you towards one goal....booking gigs.
Start working for yourself right now. Start marketing and booking gigs at this very second.
