How to Deal with Distractions
First you have to decide whether what is distracting you is more important. We have to learn to say 'no' at times.
If the distraction cannot be helped, like in the case when someone is hurt, or the computer is down, we have to learn to re-start the job at the time when the distraction ends.
If what was skipped was very important, we may have to do that first, then what we didn't manage to do, put it in further down the week, or maybe the next day is best.
Going in before hours is a good idea.
I found that staying in late when you are already jaded lends itself to slow down your work pace.
Dont be worried if you don't get the hang of it straight away, just keep on giving it a go...AND SMILE... Things seem to work better when smile and it costs nothing.
