Some people don't care about learning and just want to be right and will argue till death. Let them and leave them. Too much is wasted on them.

Don't be afraid to call off sick from work when you are truly sick. Even when they give you a hard time. Work won't care if you don't get better. Your family will.

Always pay you credit card bill in full or as much as you can. Be not a borrower or a lender.

Don't harbor ill feelings, rise above and be the better person. If they want to themselves allow it and accept.

Life is not fair, but it is good and you will deal. Don't whine be thankful.

Be aware of others around you. This world is for everyone. Remember that.

Don't stand in the middle of a busy place without realizing there are people that need around you. Courtesy!
