Yah, while growing up, many things have given me pleasure to know; in fact, am glad I encountered them as lessons in experience. This is what I've learnt over the years about the things I desire;
1) It's good to love and appreciate everything, but it's indiscipline to think you have to have everything that is good. It's also indiscipline to think that every good thing belongs to you.
2) It is good to love to learn everything, but it's wrong to think you'll learn everything. In fact, you're wrong to think you know everything, yet it's not a bad idea to think you know many things or even to know many things.
3) Age is not the determinant of happiness, but a cheerful and thankful heart. It's doesn't matter how much you have, but how much you appreciate what you have and maximize every single opportunity of happiness in it.
4) Crying won't bring rain. If crying was able to bring rain, then people in the desert lands would have been having the most well drained fertile lands of the world. So, grow up, stop crying!
5) Needs don't kill, so there is no need for being troubled when they don't get satisfied.
6) Avoiding problems is good, so avoid as many problems as you can to minimize of being troubled. There is are big differences between needs and problems, so find them out and you'll know how to live or do away with both.
7) Little things offend many people, so only smile or laugh when necessary, and when you're sure you'll not offend a friend. Un neccessary gestures may earn you enemies rather than friends so be sure you're doing the right things at the right time.
8) Humbleness with a smile will earn you more friends and favors than playfulness and violence. People love to stay in the company of serious but jolly people, playful people accomplish but little tasks and violent people distroy anything they touch, so people don't love them.
9) It cost you nothing to say "am sorry" even when you're wrong, and it is reward is awesome; in fact, it will make many people respect you.
10) Feelings are sometimes liars, but giving them time will help you know which of them is right. Sometimes the conviction of feelings comes because we've seen things in which we have or find a lot of pleasure, but not because those are the things we aspire for...
11) Just be honest, speak honestly and let your acts portray an honest character; this will bring strangers back to your house. Just live an honest life.
12) Always feel young; this feels sweet and gives life a cheerful feeling. Don't look at yourself like a boring philosopher; they find little happiness in many things - look at everything as something good if it won't heart you, and you'll always be happy... just smile to everyone, both babies and old people.
Otherwise, it's good to learn from every experience we encounter, but it's easier to learn from those who have learnt through experience... its cost is cheaper and its effect is great too. Those who learn from other people's experience are good scholars of life... they won't easily get hurt. They are the wise and humble people of this world.
