What does "Happy" means?

After our parents bring us to the world, do we exactly know what kind of life we have to lead?

In general, most people say they wish to live happily or lead a "full life". Then, what does "happy" and "full life" exactly means to all of us.

Literally, these two terms are simple to understand but they are actually very abstract and philosophical in their inner meanings. It means A to me, B to you and C to him.

In my observation, "Happy" is somewhat equivalent to "Freedom" or "Rich" or "Fulfilled" or "Healthy" or "Simply Stable".

"Full Life" relates to "Getting to the Top", "Goals achieving", "Experiencing", "Venturing", etc.

For a guy who is serious of life, he or she likes to make some life planning so that in the end they can enjoy a happy or full life at certain age. The most intriguing thing is the meanings of these words gradually change in different stages of life, usually because environmental conditions have changed.

For kids, "happy" means they don't need to do homework, or they can play all the time. To youngsters, "happy" may mean they achieve high marks in examinations or have found a charming boyfriend or girlfriend. For a thirty-something guy, "happy" may mean "earning a fortune". For patients, getting back their health can make them more than "happy".

Since "Happy" is such a personal feeling, changes with time and will be set off by different kinds of life worries and pressures, should we consider not to force ourselves to become a "happy" guy. Just let ourselves live naturally, normally, carefully--- listen to our hearts, follow our own voices but make sure we have assessed the good and bads of each decision, use the best judgement to choose the best possible solution, and say loudly to ourselves "No regrets". We have to admit to ourselves that we can never make smart decisions every time. Stupid choices are made and sometimes they are unavoidable under certain circumstances. Anyway, no big deals, we just live with them, if there are not many !
