In my mind, to base happiness on something physical is futile (like money, career, vacations, etc) because the physical world undergoes constant change. These things can increase your level of happiness and joy, in a temporary fashion. But those who do not manifest happiness from within often find themselves unhappy even when they succeed, or good things happen to them. And if they lose those things, they fall into despair.

To me, happiness is something you grow within... an attitude, as Tisha says. If you manage this, it will resonate from you. For me, it takes a lot of introspection and learning to appreciate; To see beauty and hope in something as simple as a looking out the window to see a faint, warm light shining through the rain in the darkness.

Oh and for me, balance comes more from balancing out my thoughts and eliminating extremes in my thought pattern, more so than balancing my schedule.
