Participation-A necessary for a living individual

Recently I found that sometimes I play it not for the fun but the sense of participation while I was playing LOL. During games, I feel myself fully sinking into the world, which makes feel my existence and drives away the sense of meaningless. However, Its not only for games, computer game is a strong one though, also for works, social activities, etc. that is to say, every individual needs to participate in some certain activities to feel interaction with the world. Those who can't or don't want to participate in something, they will probably commit suicide, cause that stands they let go the meaning of living.

Quite or outgoings, they all have a way to feel their existence, those who quite may read, playing instruments, unlike social activities, it doesn't necessarily involves "Talking " with people. But it doesn't mean they don't interact, they "Talk" with the world. They get response from a book, feel the same thoughts through words, even laugh or tear with novel characters, get inspired by others silently. For something like a guitar, the sound is the world talking to him, no literal words needed. For outgoings, they prefer being around with people, the alive image and voice of human makes them fullfilled, and it tells them "I am doing things and I am alive."

All in all, we all need to certain we are doing something, happy or painful, we just need. The first and for most pain is a person can't feel meaning of his life and has no intention to change the condition, nothingness drains a man's life.
