Make your preparations for the next day's interviews the prior evening so that you do not waste time during the business day. Above all, do not while away time on the golf course, in front of the TV set or waiting for the phone to ring with a job offer. It helps to establish a personal routine during the time you are unemployed. That should include exercise, waking up at your usual hour and scheduling some periods of recreation. Keep up your normal social contacts.
Some people react to unemployment by drawing within and shunning their usual social contacts.
You should not try to hide from the world. There is absolutely no shame attached to being unemployed, especially now when so many people have become victims of mass layoffs, through no fault of their own, in the wake of downsizing. The contacts you make on social occasions can provide important job leads, so you should not wall yourself off from those sources. Do not take a vacation. Taking a vacation takes you out of the job market.
