I have no confidence

I agree that negative thoughts are a self-fulfilling prophecy.  If you go to a job interview with an attitude that you are too stupid to get the job & they probably won't hire you, that will come across in the way you project yourself with no confidence and they won't hire you.  Not that it's a guarantee that you will get hired--I am looking for a new job.  I recently got a few job interviews and I didn't get hired but I look at it in a positive way.  I was told that out of maybe 100 people who applied for the job they only picked 25 to interview so at least I am in contention--these were jobs that I know I could do a good job on too.  But you just have to carry on--you can't make it that you were terrible.  You have to realize that there are probably a lot of qualified people who are applying for jobs and they can only pick one.  You can't be that stupid if you have been able to hold onto the same job for years--if you were terrible you would have been fired by now.  so think about it--what have you learned on this job?  What are your good qualities that you can emphasize--even if it's things that you think are small, like you are always on time, you don't take a lot of sick days, you are nice to customers, etc. 

Besides, if you think these negative things about yourself--what can you do to improve yourself?  if you think you are stupid, what are you doing about it?  Do you just sit around doing nothing or do you read books?  Have you taken classes, if not in college, then how about training in new things, like learning some computer system?  You could always start out in adult education or taking a class at the local college that is non credit, then you wouldn't have the pressure of grades.  if you think you are ugly, well let's face it, not everyone, in fact most people do not look like models.  I know there are things about myself that I'd like to change, but everybody can make the best of their features.  You know Adele is overweight and in the entertainment industry there's so much pressure to be thin, but she has this great attitude like this is who I am, who cares?  so she gets clothes that look good on her, she does her hair & makeup & she looks great.  Do you buy decent looking clothes or just horrible looking things?  Do you have a nice hairstyle, makeup--can you get some friends to help you out?  Everybody should go out looking their best even if they aren't the most attractive person.  It will give you more self confidence.
