The best thing for being sad is to learn something. This is the only thing that never fails.
You may grow old and trembling in your anatomies, you may lie awake at night
listening to the disorder in your veins, you may miss your only love, you may see
the world around you devastated by evil lunatics, or know your honour tramples in
the sewer of baser minds. There is only one thing for it then -
Study
" ... at this very moment the search is on - every numerical analyst
has a favorite preconditioner, and you have a perfect change to find a better one."
