I appreciate your heartfelt comment and I will check out the book.
If I lived in 1221 I would probably be a monk or something...lol...maybe I can still be...I don't really have the religion though...kind of nice the idea of having a life with few worries that inertia today will lead to future pain.
A big part of mindfulness is narrowing down your reality to only this moment, because that is really all that's real. The past isn't real and the future isn't real. It's not about accepting "your life" because that's not actually a real thing. Right now is all that is. All context is actually fully contained in this moment. So one can accept and be at peace with what is happening right now and see it for what it is, then, thus informed, make and follow a plan. But each moment has it own independent meaning and is an ending in itself. There is no final goal because it's always right now, so the rational approach is to always pay attention to what IS.
Because life is about happiness? If you find what makes you happy every day, why die and have these great days going for waste? With this mindset, the bad days also don't become that bad, because you have the experience of the great days of the past.
There's a good book called _The Path to Nibbana_ that describes a practice I've found helpful. It's about reducing craving. Reducing craving allows there to be contentment and equanimity, and a different kind of happiness than most people are used to in that it doesn't depend on anything. In any case, whatever you do, I hope you'll feel better.
