When you are seeking happiness through your action, you are always enslaved to the external situation. As long as you are enslaved to the external situation, you will always be in some level of suffering because the outside situation is never going to be hundred percent in your control.

If happiness always depends on something expected in the future, we are chasing a will-o’-the-wisp that ever eludes our grasp, until the future, and ourselves, vanish into the abyss of death.

The one who would be constant in happiness must frequently change.

We insist that we can't possibly be happy until tomorrow, when things change. But if happiness is possible tomorrow, it is also possible today.

Her happiness, like that of most of us, was ever in the future, — never reached but always coming.

Until we have inner permission to be who we are, we will always be searching for it in the outside world.

For man is always bound so long as he depends for his happiness on a partial experience; joy must always give way to sorrow, otherwise it can never be known as joy.

Everything on earth is in continuous flux: nothing preserves a constant fixed form, and our affections towards external things pass and change with them... There is nothing solid to which the heart can attach itself. Also, there is scarcely a pleasure here below which does not pass; as for enduring happiness, I doubt that it can be known. In our most vivid joys there is scarcely an instant at which our hearts could truly say: would that this moment might last forever; and how can one call that transient state happy which still leaves our hearts disturbed and empty, which makes us regret something beforehand or still desire something afterwards.

Everything is in constant flux on this earth. Nothing keeps the same unchanging shape, and our affections, being attached to things outside us, necessarily change and pass away as they do. Always out ahead of us or lagging behind, they recall a past which is gone or anticipate a future which may never come into being; there is nothing solid there for the heart to attach itself to. Thus our earthly joys are almost without exception the creatures of a moment...

as long as we structure our lives in a way where our happiness is dependent upon something we cannot control, then we will experience pain.

As long as you live, there's always something waiting; and even if it's bad, and you know it's bad, what can you do? You can't stop living.

When we look back at our experience, we can see so clearly its ephemeral, dreamlike nature. Yet when we look ahead, when we look to the future, somehow (and this is the great enchantment) we get dazzled by all the possibilities that are there waiting for us as if the next event in our lives, the next situation, the next project, the next relationship, the next meal, even on meditation the next breath ... we live our lives in anticipation of the next hit of experience as if the one that's coming will finally do it for us. What's so strange is that nothing up 'til now has brought that sense of real completion or fulfillment. So why are we so seduced into thinking that the next one will? This is a very strange phenomena.

Happiness is a constant work-in-progress, because solving problems is a constant work-in-progress.

Everything fluctuates on earth; nothing remains in a constant and lasting form, and those affections which are attached to external things necessarily change with their object. We are ever looking forward or backward, ruminating on what is past, and can return no more, or anticipating the future, which may never arrive; there is nothing solid to which the heart can attach, itself, neither have we here below any pleasures that are lasting. Permanent, happiness is, I fear, unknown, and scarcely is there an instant in our most lively enjoyments when the heart can truly say, May this moment last forever!!! How then can such a fugitive state be called happiness, which leaves an uneasy void in the heart, which ever prompts us to regret something that is past, or desire something for the future?
