Don’t pursue your dream…is something I’d never say.
I’ve seen enough success–and failure–stories to know that I am not ably to reliably predict what someone’s career trajectory will look like. Actually, I’ve seen enough to know that I don’t think anyone can.
Actually, I think the “don’t pursue your dream,” people are even more nefarious, because they want to take credit for talking you out of it, AND take credit for your success if you succeed. (The logic goes something like, “If they heard me and quit, then they really didn’t want it. If they heard me and kept going, then I lit a fire under them to prove me wrong.”) That’s ridiculous. If someone tells you not to pursue your dream, they deserve no credit whatsoever in any success you might eventually have.
Pursue your dream. Pursue it. And don’t tell anyone not to pursue their own.
