NINE WAYS TO GET MORE DONE

1.  Avoid meetings that lack an agenda.
Meetings can only be productive if people know why they're meeting in the first place.    An agenda provides focus and purpose.    The lack of an agenda guarantees meandering conversations that dive into rat holes.    They're a waste of your (and everyone else's) time.
2. Never pick up on an unknown caller.
Unless you're working in telesales or product support, there's no reason why you should ever take a call from somebody you don't know.    After all, when was the last time you took an unexpected call that was truly important?    Days? Weeks?    Months?
3. Hone your email program's sorting rules.
It takes time and energy to change gear to sort through (and respond to) a long list of disconnected messages.     Most email programs allow you to route different types of messages into folders, where you can review and respond en masse rather than piecemeal.
4.   Periodically disable email and texting.
When you must do creative work or absorb complex information, the last thing you need is your computer and phone chirping and beeping for your attention.    Whatever it is, it can wait until you've finished the task at hand.    Trust me.
5. Give chatty people at work short shrift.
For some people, a day at work means an endless coffee klatch.    They wander the halls searching for somebody, ostensibly to discuss business but really just to chat.    Don't let these time leeches hobble your success.    Just say no, or wear ear plugs, or if necessary, just walk away from them without explaining why, they will avoid YOU after that "because you are so 'rude'."
6. Reward your body with high-quality fuel.
What you eat determines your energy level, and your energy level determines how much you can get accomplished.   Eat salads, greens and fish (and no "white food" at all).  Sugary treats provide a quick energy boost but then create an even deeper dip.   Heavy foods take energy to digest, leaving you with less to use.  Soda causes depression.  Drink water.  An added bonus, eating properly is CHEAPER than eating junk, you can use the additional money to go out, pick up a new hobby, travel or invest it.  You'll also LOOK better than ever before.
7. Take a five-minute walking break every hour.
The human body is not designed to sit for hours at a stretch.     Attempting to do so inevitably creates aches and pains (especially in your back and neck) that leech your energy as your body tries to compensate and heal them.   So get up and move!   Use a timer if you have to.  Or, work like they do in europe, on for three hours, off for three hours, on for three hours.  And take a nap in between (outdoor nap with some sunshine would be best).
8. Make your decisions quickly.
Most people waste an extraordinary amount of time obsessing about (and second-guessing) their decision making.    However, you're always better off making a good-enough decision quickly than waiting for an imaginary best decision.
9. Completely disconnect for 12 hours every day.
If you stop pretending to be productive when you're eating and sleeping, you'll be far more productive when you're actually working.     Being always available is an unfailing recipe for stress, illness, and bad decision making.    Give it rest.
