As an Atheist, I would say that the meaning of life for to me is to first accomplish goals. Then move onto living a prosperous life. Make sure your name echoes through time for decades, centuries. Like Albert Einstein. Sound familiar? Think about it. If you die, and no one but your family and friends knew, or cared? That is quite depressing. And if that happened to me? I failed my purpose as a human being on Earth.
To accept Jesus Christ as your Lord and Savior; then identify the gifts that He has given you; and then use them to pursue the plan He has for your life. This is truly the meaning of life. Jesus said, " I am the Way, the Truth and the Life".
Life is “Karma” means, “Serve the duties”, your goal is to perform tasks that comes in the way of your life; your “Karma” will define you at your end.
Do not get frustrated at failure, try once more. Look at your surroundings, Find out the expectations on you! Try to fulfill the expectations on you. Never expect for returns or personal gains, try to draw such a line that will make you immortal even after the death of your body.
The real meaning of life is not just bothering about YOURSELF.It's for realizing the worries of others.Sacrifice yourself in doing good to others.Thus the life is not to do anything for fame or something.It's for our satisfaction.At last our goal is to manifest god in us.i.e. the divinity in fellow men.
