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!

Delete the negative people from your life. Keep the positive people close to you. Why waste time and energy on those that stay negative?

Do your own thing! Don't worry what others are doing.

Don't ever believe anyone that says you can't do something when it comes to your dreams and goals. They just never had someone to support them to do theirs.
