One of the themes in the book of Ecclesiastes is that "without God, life is meaningless and empty".  Keep in mind the book of Ecclesiastes was written by a man who had it all - wisdom, power, wealth.

Some thoughts:

"Like the fool, the wise man too must die!"

Death is the great equalizer.

Everything in life is meaningless in the whole scope of things.  The only thing that really matters is salvation in Jesus.

"Always be clothed in white, and always anoint your head with oil."

Be righteous and live an anointed life.  After all we are anointed with the Holy Spirit.

Happiness is dependent on circumstances. True joy comes from God and brings contentment no matter what the circumstances. (see the website for Walking in the Word - Joy Parts 1 and 2.)

We don’t find meaning in life through money, pleasure, work, or popularity. Meaning in life comes from doing things that are part of God’s purpose for us. 

To be in His will is the greatest place to be.

How do we know how to be in His will?

Simple - talk to Him, listen to Him, and read His Word!
