less is more
I was recently without my laptop computer for a whole two hours.
I found the experience quite liberating.
I cleared my drawers of three years' worth of accumulated clutter and paperwork.
I was then able to sit down quietly and read a whole chapter of a book (Jonathan Lewis' Practical Oracle 8i) on Oracle partitioning which has a fantastic analogy with the Encyclopedia Britannica. This is very useful because when non-technical people ask you about partitioning, this is exactly the analogy you should use (as opposed to 'buckets' and 'partition elimination').
I then made a list with pen and paper of things to get done. Old technology, admittedly.
I then called some people on the telephone and spoke to them.
Then, finally, I got bored and pestered my colleagues, begging on one knee for just 5 minutes on their computer.
