#3. Never turn down an open bar. Seek them out and make them a priority. Indulging in open bars when you’re older isn’t appropriate because a) people will think you have an alcohol problem and b) you’re supposed to have enough money to afford your own alcohol.
#4. If you’re unhappy and someone offers you a way out, take it. You don’t owe your first job years of loyalty and your first-born; you don’t have to stay in your city just because you’re on a first-name basis with the bodega guy. Do what feels right; the initial fear will give way to excitement.
