Avoid falling into the trap of living in hope that the person who rejected you will change his or her mind. There is nothing wrong with a faint hope that this may be the case but to be consumed by the possibility will cause you to put your life on hold and not progress on your own terms. Do not feel that you need the person to change his or her mind for things to turn right for you––you will only end up torturing yourself. If a person rejected you for a lack of attraction to you, that will likely not change and forcing it will only bring unhappiness. If a person rejected you because he or she didn't feel that you fitted the corporate culture of the workplace, that's unlikely to change if your CV is filled with the opposite of what they're looking for. It's best to simply accept that that opportunity is passed by and to move on, wiser in the knowledge of where you are likely to be more successful in making your future requests.

8)
Review the possibilities. In some cases, you may have a lot of control over why you were rejected. For example, perhaps you were sloppy in the way you filled out a form, or perhaps you didn't complete the right course to get promoted. In such cases, take the constructive advice that the rejection is offering and build on it to improve your lot. There is absolutely no need to sabotage your future––there are always things you can actively change. This includes such things as getting a job or promotion, sharing your portfolio around, nailing a team position and even relationships. And while you can't change whether or not a person is attracted to you, you can definitely improve your own grooming and manners, which might just improve the other person's feelings toward you. Even if it doesn't, provided you do things to improve your own sense of well-being and confidence without relying on any person to bring you happiness, then you'll attract more positive opportunities into your life.
Sometimes you need to ask why you were rejected, especially where there are no reasons given. Don't be shy. If it's a commercial transaction, anything from being accepted to business school to having your necklaces displayed at a craft show, there will always be people in charge to whom you can talk directly or by email. They may well give you tips or advice on what you need to do to improve your chances next time round. Most of all, don't be afraid to ask them if they're willing to coach or mentor you, or at the very least, to review your application/work/efforts, etc. before submitting or requesting next time. Most people are genuinely impressed by a person willing to learn and improve. (Just remember to be reasonable in how much you ask of others––everyone is busy.)

9)
Try again. In most cases, it is worth trying again. Perhaps the main exception to this is in trying to force love––only try again to ask a person on a date if you're sure that both of you have reached a greater understanding and awareness between one another and you're approaching the new request with maturity and full acceptance that rejection may well be the outcome again. In the case of jobs, sales, applications, etc., trying again is usually the only way to get ahead.
Some clubs, jobs and the like will ask you if you have applied before. Don't be dissuaded by such a question––it is only in the cases where the place makes it clear that "previous applicants need not apply" that they won't give you a second chance. Even then you might do well to get hold of someone in charge and find out why this hurdle exists and how you can get around it. Tenacity should be your number one motivation when overcoming rejection.
Be aware that rejection is sometimes used as a filter to get rid of people who lack enthusiasm and determination. In some cases, the fact that you turn up and won't take no for an answer will count very much in your favor!

Always remember, you do not need anything external to feel happy. Things can only bring you temporary happiness. The only permanent happiness is found in understanding this and in acknowledging the awesomeness of being alive.
