Arguing is such a waste of time. Just plain ignoring is so much more efficient.
I set a goal and talk to people who are supposed to advice me.
The question I ask in the face of unsolicited advice is , ” IS this person someone I want to be in the future sometime or has she coached someone who I would want to be in the future sometime?
If the answer is NO. Smile and Nod. He / She and all her so-called “experience” has nothing to offer you. Nothing.
Move on to seek people who have actually done somethings.
