Value your life, don't lose it. Don't even think of suicide because many people wished they had enough time to accomplish their dreams. You still have a chance to do that so why give up?
Value your health. Take good care of yourself because many people pray just to be healthy like you. Health is wealth.
Value your freedom because so many people are willing to spend all they have to buy their freedom. If you doubt this, go to the prisons.
Value your parents irrespective of their status, whether rich or poor. If you think I'm wrong then go to orphanages and see how the kids wish they had someone they could call mother or father, no matter how bad they are.
Value your friends because they are not easy to come by. Be a good friend too. Be left alone on an island for a year and see if you will not contemplate suicide.
Value the food you eat, no matter how cheap because so many people have enough money to buy it but can't eat it because of their health.
Value your job because so many jobless people out there envy your job and wish to have it.
Value what you have because you might not have a chance to get it again. They say a bird in hand is worth 10,000 in the bush.
Value the little things you are given because they have the tendency to attract bigger ones.
Value yourself, value people and value the things around you, no matter how little. That's the best way to live and enjoy life.
