Have You Figured Out That It Resides Inside You

Are you happy, can you provide proof?
Do you still see through the blameless eyes of youth?
Somehow unaffected by reality of truth
or shrewdly turning a blind eye in your pursuit?

Happiness is fleeting, happiness is mine,
happiness is yours, happiness can fly,
happiness may walk in and out on life.
Can you complete the pursuit before you die?
