A quick word about about attitude. If you're in the job market (and you're always in the job market, passively or actively), you must become aware of your aura, your energy, your attitude.
And you have to learn how to manage your physical impression.
It's hard to write about this. There is no concrete study I can point to. But I know that if you're negative, depressed, bitter, angry, distrustful, skeptical, sad or otherwise unpleasant, you hurt your chances with potential employers.
I'm not saying your feelings are invalid -- far from it. Layoffs are unfair. The job market is rife with ageism, sexism, racism and any other type of "ism" you can think of . The slow economic recovery is downright depressing. You haven't gotten a raise in ages.
But you can't let these emotions overtake the happy, confident you. Bitterness announces itself like bad cologne. Once it's in the room, it's hard not to notice. And potential employers, or customers or contacts can't wait to get away from negative energy, and will be reluctant to invite bitterness into an already stressed workplace environment.
So shake it off. Exercise. Laugh. Listen to music. Read good books. Go to church (or not). Turn off the evening news. Do what you do to stay positive.
