Life is like the stock market. You invest your currency into a company and either gain or lose. You invest your time into a thing--whether it is a skill or a subject or a thing--and you either gain or lose something.

Invest your time in skills, for they are sure to serve you. Actually, not all of them do. Who needs to be able to tell the difference between two rocks but geologists? Who needs to be able to play the viola or the violin or the piano if all you're ever going to do with it is drop it? Who needs to be able to sing if you can just listen to music?

Invest your time in knowledge, for knowledge is sure to help you. Not all knowledge though. Just the knowledge that you need to get into college. This does not include knowing how to take care of a baby, how to pay for bills, how to apply for internships, how to live a fit life. Those won't ever help you.

Invest your time in your health, for health makes life. The healthier you eat, the more energy you have, the more you exercise, the prettier or handsomer you will be, and the more likely you will land a better job and get a better spouse and learn better. By healthier I don't mean more, I mean healthier. The fruits, the vegetables, the protein, the healthy things. Don't grab that bag of chips at 12 am at midnight, and don't have five to ten meals a day. Have the consistent three or four at around the same times. Exercise at least three hours a week. Spread out the exercise too; don't exercise three hours one day and rest the rest of the days, but at the same time don't exercise five minutes at a time. Thirty minute increments are great for exercise. And don't forget to stretch the body. Stretching is good for sore muscles and helps with relaxing.

Invest your time in humor, for humor makes the person. Whoever can live without humor, I applaud and pity them. They must live a horrible life. Just make sure not to offend people. Don't tell the black joke or the viola joke. Everyone hates those. Tell the joke of the train conductor being a bad conductor of electricity.

Invest your time in love, for love brings good karma. Love is worth it. Learn to read people, to hear what they're really saying, to understand them, to help them. Take a human psychology class or two. Learn how people act and why they act that way. It will help with all relationships. But remember, don't only help others. That makes the investment lose out.

Invest your time in yourself, for you yourself make your own worth. No matter who you are, you are worth something. You can be the billionaire or you can be the beggar on the street. Sure, everyone has his or her own disabilities and weaknesses. But we all have our own strengths too. It's the whole the blind man hears better or the deaf man has the better sense of smell. Find your strength and develop it to be outstanding. Develop it so that people will need you.

Invest your life's money wisely.
