When my sons dropped out of college many years ago, they wanted to play music and came very close to a contract deal. They finally decided that it wasn't the life they wanted and both went back to school. Both now have masters and both graduated magna cum laude - because that is what they wanted ... not what was expected of them. If they hadn't taken that time off, they may not have done so well and would always wonder "what if".
If you have the support of your family, as a father, I would encourage the dream.
