I am 42, and I a hate to admit it neither do you get the answer at this age either
I remember a line from an old movie "The Last Starfighter" , this old janitor gives an anology between life and a rollercoaster ride, with its up and downs, and then says :"When an opportunity arrives, or you get your chance, hold on tight and enjoy the ride!"
Take opportunities to enjoy whatever you can while you can, and at the end of the day, say "i lived a good life".
Rather than be someone who says, "I should have", or "I wish I had"
Give your life meaning, and you will get the meaning.
THe formation of Earth and the coming into existence was a statistical and mathematical cerainty. In teh infinite expanse of time it is impossible that the earth and we humans would not have come into existence. We are coplex organisms which have evolved over millions of years. We get born, live a while and then we die. When we die, thats the end, there is no everlasting soul that goes to some place in the sly where teh Mojitos are free. Thats it. LIfe is therefore without any meaning...except what you from the time you are born till you die....IE life is what you do while you wait to die. You can sit in church every Sunday and pray for the strength to deny yourself the worldy pleassures that you are supposedly goig to enjoy in a non-existent afterlife...or...you can live your life to the fullest so that when you have grandkids you have plenty of stories to tell them..I have plenty..
