Life is a circle you feel lost then you find your way, only to find its not your way, then you feel lost again, and it goes on till you die. Know this that you will never find any deep meaning to life, its all there it is to life. Its simple give happiness to others, be honest and just enjoy your time here doing things you want to do and then leave in peace. Be happy or not its immaterial, you can't be in one state for long anyway. We are all but a pale blue dot in the vastness of the sky. https://en.wikipedia.org/wiki/Pale_Blue_Dot
