business lessons

I was wondering if anyone here would like to share anything they have learned by experience. something that helps you in business.

I will share mine: It's easier to say "yes" than to say "no"

for example, if you are talking to a seller, which question is better?

"Do I have to pay for shipping?"
vs.
"Is shipping included in your price?"

You might ask "what the hell is the difference?" I am glad you asked.

It's easier to say "Yes" than to say "No"
so if you ask the first question, the seller will say "yes, it's $5"
if you ask the second question, the seller will say "yes, free shipping"
people simply love to say "yes"
Now you tell me other things that help you save money.

Something I've learned to live by: fail early to succeed sooner. Mistakes are seriously the best way to learn.

Also, there are always going to be difficult customers regardless of what service or product you sell. Don't let that get to you, just address it professionally and move on.
