Purpose of life

I was searching in internet about purpose of life , few lines caught my attention, some great person suggested below steps to find purpose if life.

1.Take out a blank sheet of paper or open up a word processor where you can type .
2.Write at the top, “What is my true purpose in life?”
3.Write an answer (any answer) that pops into your head. It doesn’t have to be a complete sentence. A short phrase is fine.
4.Repeat step 3 until you write the answer that makes you cry. This is your purpose of your life.

I tried for enough time , didn't get any answer which makes me cry. In recent days I am thinking too much about life purpose and I became passionate about this topic. I am hoping that at least by end of this life I may find answer. Atheists like me will ever find answer to life's purpose??

I read somewhere that if you believe in god you can't become god, am I trying to become god?? If at all god exists does he believe in God?? If yes, whom does he believe?? Where this cycle started?? Cycle ......froget about life cycle, I have a cycle in front of me which is giving some exciting moments when I ride on it.Going to ride in this midnight , now the time is 1 AM.. Attached is the photo of my cycle.So many irrelevant stupid or genius questions, brain taking too much and energy for all these.

Going for cycle ride.
