What is life really all about?

Is our life here on earth purely for the striving of enjoyment? Are we to work hard so that we may achieve alot? Or are we to try to live a humble existence in all we do, being content with what God provides for us? Alot of people work hard all their life, but by the worlds standards they don't really achieve much. So what does that say about our life's purpose? I think we are here to lead good lives within God's plan for us. Yes, to enjoy and be grateful for all God gives us, no matter how much or little it may seem to the "world". More importantly, I think God wants us to share, with others, all He does bestow on us. He wants us to share of ourselves, our time, our knowledge, and the love He has for all. We are to serve God by sharing the good news of His Son, Jesus, and our salvation through Jesus. In this we all have in common; God's peace, joy, and love are given to each one of us in abundance. No one who recognizes God will be left out. Every one's idea of success may be a bit different, but real success and happiness is found through Jesus and our eternal life with Him. This is everlasting and the only thing that goes with you in the end.

Ecclesiastes 3:13

"For everyone, moreover, to eat and drink and enjoy the fruit of his labor is a gift of God. I recognized that whatever God does will endure forever, there is no adding to it or taking from it. This God has done that He may be revered."
