If this isn't enough to get the job done there's something wrong. Either your boss is not being realistic about how much can be accomplished in a day or you may be spending too much time trying to do "perfect" work. Being in the wrong job may [also] cause drag in your efficiency. There are always times when a tight deadline forces you to speed it up, but that should be the exception not the rule.

SM: What are the best ways for people to be more productive during the day?
LF:

  1. Get a good night's rest.
  2. Do work that you love.
  3. Plan your work and work your plan.
  4. Take scheduled breaks.
  5. Don't spend unnecessary time trying to perfect perfection. Know when "good enough" is good enough.
  6. Build relationships before you need them so that when you do need help, people are willing.
  7. Routinize as much as possible.
  8. Let calls go into voicemail and close your e-mail when working on a tight deadline.
  9. Exercise regularly.
  10. Resist the urge to jump in and start projects before you've planned them out.
