New Century Version
9 Enjoy life with the wife you love. Enjoy all the useless days of this useless life God has given you here on earth, because it is all you have. So enjoy the work you do here on earth. 10 Whatever work you do, do your best, because you are going to the grave, where there is no working, no planning, no knowledge, and no wisdom.
Time and Chance
11 I also saw something else here on earth:
The fastest runner does not always win the race,
the strongest soldier does not always win the battle,
the wisest does not always have food,
the smartest does not always become wealthy,
and the talented one does not always receive praise.
Time and chance happen to everyone.
