Read the Bible

¹ Invest what you have,
    because after a while you will get a return.
² Invest what you have in several different businesses,
    because you don't know what disasters might happen.

³ If clouds are full of rain,
    they will shower on the earth.
A tree can fall to the north or south,
    but it will stay where it falls.
⁴ Those who wait for perfect weather
    will never plant seeds;
those who look at every cloud
    will never harvest crops.

⁵ You don't know where the wind will blow,
    and you don't know how a baby grows inside the mother.
In the same way, you don't know what God is doing,
    or how he created everything.
⁶ Plant early in the morning,
    and work until evening,
because you don't know if this or that will succeed.
    They might both do well.

⁷ Sunshine is sweet;
    it is good to see the light of day.
⁸ People ought to enjoy every day of their lives,
    no matter how long they live.
But they should also remember this:
    You will be dead a long time.
    Everything that happens then is useless.
⁹ Young people, enjoy yourselves while you are young;
    be happy while you are young.
Do whatever your heart desires,
    whatever you want to do.
But remember that God will judge you
    for everything you do.
¹⁰ Don't worry,
    and forget the troubles of your body,
    because youth and childhood are useless.
