Hi, I think you meant to write thing not thind. I would say it's the miracle of a child being born.

do something you enjoy

it's friendship and love.

i think is love

I would have to say...desire. When someone 'desires' something they usaully work to get it. If it is change themselves, the things they do or their surroundings. Desire triggers ambition which would dictate love, job, friends, home, knowledge, inventions, appriation of something different or a family.
