A P.I.T.A. client is not worth it. You end up spending your time working on someone who is never happy and disregard the better clients who don’t complain.
Don’t undercut your price. You work harder, have less money and the client thinks you are only worth that much. If you are not confident in yourself enough to raise your fees, then you should not be in business.
Barter = Bad. Both parties always feel like they got the short end of the stick.
Be kind to people always.
Your clients don’t like you as much as you think they do. Think of who you would stay in touch with if you sold the business.
Once you screw up a client, drop them. They will always remember that time when things went awry and will remind you of it as soon as things seem off again.
Don’t let the customers get to you, if you work in retail or the service industry. Just remember that they’ll be gone in a few minutes.
Never give a lot of details about family, friendships. Be very neutral as it can be used against you in certain scenarios.
