We want the sun to shine all night, and when it doesn't, we create cities that never sleep. Seeking a continuous energetic and emotional high, we use everything from exciting parties to illegal chemicals. But natural ebbs -- the darkness between days, the emptiness between fill-ups, the fallow time between growing seasons -- are the necessary complements of upbeats. They hold a message for us. If you listen at your life's low points, you'll hear it, too. It's just one simple, blessed word: Rest.
-- Martha Beck

After working continuously a number of hours we tend to fatigue, in an effort to get more done, one of the first things we're willing to sacrifice is sleep.

But consider this disturbing fact: Sleeping even a single hour less than our bodies require reduces our cognitive capacity dramatically. Much as we try, we can't fool our bodies. Consider this statistic: Even a single hour less sleep than you need to feel fully rested takes a significant toll on your capacity to think clearly and logically when you're awake. Sacrificing sleep is self-defeating. So, what's the solution? It's not to manage your time better. It's to manage your energy. 

-- Tony Schwartz

Energy Suckers (a.k.a Negative Nancies, Debbie Downers and Sad Sids). These are the people who find the cloud around every silver lining. If you can't cut them out of your life entirely, turn your interactions with them into a game. When my neighbor says, "I hate this horrible weather!" I say, "Isn't horrible weather great? It means I don't have to wash my car!"
-- Donna Brazile

Every single person I have met tells me not only about their own clutter problems but about those of a family member, or those of a friend. Nobody seems immune. The stories are not dissimilar -- papers and magazines run amok, garages overflow with unopened boxes, kids' toys fill rooms, and closets are so stuffed that it looks like the clothing department of a major retailer is having a fire sale. The epidemic of clutter, the seeming inability to get organized, and the sense that "the stuff" is taking over affects us all. We are at the center of an orgy of consumption, and many are now seeing that this need to own so much comes with a heavy price: kids so overstimulated by the sheer volume of stuff in their home that they lose the ability to concentrate and focus. Financial strain caused by misplaced bills or overpurchasing. There is  a deeply personal response to the feeling that the rest of the world is out of control. Peter Walsh

When we are busy focusing on what we don't have, we don't pay attention to what we do have. Wanting is different from having. Wanting is in the future. It is based on an idea of what might make you happy in five minutes, tomorrow, next week. But having is here, now. Most of us don't let ourselves have what's in front of us, so we're always wanting more. When you don't let yourself have what you already have, you are always hungry, always searching, always restless.

Like our need to fill stomach after few hours,we also need a dose of reviews-view how your life is going on

• Step out of the time dimension as much as possible in everyday life. Become friendly toward the present moment. Make it your practice to withdraw attention from past and future whenever they are not needed.

• Be present as the watcher of your mind -- of your thoughts and emotions as well as your reactions in various situations. Be at least as interested in your reactions as in the situation or person that causes you to react.

• Use your senses fully. Be where you are. Look around. Just look, don't interpret. Be aware of the silent presence of each thing. Be aware of the space that allows everything to be. Listen to the sounds; don't judge them. Listen to the silence beneath the sounds. Touch something -- anything -- and feel and acknowledge its Being. Allow the "isness" of all things. Move deeply into the Now.

-- Eckhart Tolle
