# all the deeds that my hands had accomplished

"all that I had accomplished"

# the labor that I had done

"the hard work that I had done"

# like chasing the wind

"are as useless as trying to control the wind". See how you translated this in Ecclesiastes 1:14. 

# There was no profit under the sun in it

"But it had no profit under the sun"

# under the sun

"on the earth". See how you translated this in Ecclesiastes 1:3.
