Another valuable lesson I learned as a teenager was not to get greedy when selling. I've flipped countless things on the side for extra money + fun ever since freshman year of high school. The money is made on the buy, not the sell, yet my inner Greek would unconsciously try to get unrealistic bargains on both ends.
If you have a buyer in cash for a car and they're offer is very fair + close to asking, TAKE IT. Guaranteed sale > squeezing every drop of juice out of a cash buyer.
On a smaller scale, I learned this the painful way when I was gifted a 1 year transferable gift card to a local fancy health club. Had a value of like $800-900 at a time where that money would go a long way for teenage me. Got a few cash offers in the $300-500 range.......but no, lets just leave it an extra week, just an extra $50, someone will offer it......
Well, most of those clubs have since closed and I couldn't sell that membership for a can of Sprite right now
have kept the certificate in my desk drawer all these years as a reminder that acting like an arab market trader on every deal does not make you a good negotiator, it makes you a greedy ass.
This is more common with buyers who stroke themselves to sleep at the thought of fleecing someone, like it's some big accomplishment to expend a ton of energy to wear out a seller just to pocket some extra scraps.
