text: i have a hard time keeping focus on my work. what should i do?   well, um, what were we talking about?  start with getting a good night sleep.  shoot for 8 hours.  if it is impossible then try to find a way to take a nap during your work day.  research is proving that a 20 minute nap mid day works wonders.  in fact, when i ran a lab i asked my boss if it was ok not to take first break but bump it into my lunch break.  that made 45 minutes for lunch.  i'd nap for 20 then have 25 min for lunch.  oh, i'd also tell him i was going to nap for that time, he thought i was weird, but he had to admit my work was the best he had seen.  and stay away from sugar, caffeine and other wake-up drugs.
