I am not in radio but knew some radio people over the years. Here is what I learned....be ready to move all over the US at a moments notice, don't buy any real estate, try to rent month to month, save as much money as you can for the moving expenses, keep your expenses low (don't have kids), travel light, prepare to work graveyard shifts, keep smiling, consider radio rehab because it gets in your blood, don't quit your day job, keep a focus on what direction you want to go but be ready to take detours, get into any related work fields, be flexible to be involved with rock, country, religion, spanish, hip hop and sports, get a good education (but keep those student loans low) and pray for luck. Now you see why I do not work in radio. (but I love radio)
