A concise definition of mindfulness is inherently reductionistic, squeezing into a few shabby words the limitless natural capacity for awareness & open-heartedness. Who would spend a lifetime practicing mindfulness meditation if one could "get it" from a definition? So mindfulness is a natural capacity, a method or practice for cultivating this capacity, as well as a way of being in the world. Analogies can be drawn between a person practicing mindfulness & a computer that could intentionally, continuously, upgrade it's own operating system: http://mindfulnessforeveryone.blogspot.ca/search?q=operating+system Another analogy is how a novice swimmer relates to water compared to an expert swimmer. The novice is afraid of the water & exerts a lot of effort in fighting the water. The expert likes the water, which naturally supports her, and she exerts minimal effort to propel herself forward. The expert open-heartedly engages & collaborates with - instead of fears & fights - the environment. Friction, noise, wasted effort is minimized, while quality of life & efficiency is maximized. Even intelligent, well-educated folks may be unable to distinguish betweenbeing swept away by the torrential river of lifefromsurfing the waves. But when the status quo no longer satisfies, one might investigate mindfulness.
We gravitate tothe quick easy fix no matter how complex the problem. Gobbling down a chocolate bar when hungry, gives a sugar-high, quickly followed by a crash. And so it goes for all attempts to feel good fast - short-term gain, predictably followed by chronic, long-term pain.

It's a slow, lifetime journey of discovery & deepening, learning to embrace all of life. Practice often feels ordinary, yet brings occasional awe-inspiring highs, and carries us safely through occasional hard times. We discover & learn to trust an inner compass, guiding us through the full spectrum of human life. It's NOT a quick fix, NOR is "bliss" (though it sporadically happens), the goal.
