To maintain self esteem be honest; loyal to family and friends or your partner; be there for people that have been there for you. Be kind and considerate, but do not let anyone take advantage of your good character. Know right from wrong and stand up for the right things in your life or for a friend that is not being treated fairly even if it means you are not going to be popular with others regarding your decision. In the love department never let the opposite sex use you in any way and know that you are in full control of what you do in your life and aim for the stars. Bed hopping (not accusing you) will lower the person's self esteem sooner or later and certainly the people they are sleeping with will have little respect for that person. Be the best you can be as a caring human being, but realize you or anyone else are not 100% perfect and we all learn from our mistakes.
