In one sentence, describe what the following article is about:

With rejection sensitivity, you can easily get caught up dwelling on people who reject you and forget about those who embrace you. Make a point to spend time with people who value who you are as a person.  Whether it’s friends, coworkers, peers at school, or family members, make an effort to connect with people who love and care for you. They can help balance the scales against any rejection you feel from others. If you don't have strong relationships, meet some new people. Volunteer and help out in your local community. Join an organization or club. Strike up a conversation with the wallflower at a party. Become an advocate for those who are being bullied. People with rejection sensitivity often go into social situations expecting to get the cold shoulder. In many ways, this can be a self-fulfilling prophecy. If you enter a situation in bad faith and with a negative attitude, you are more likely to get the same in return. However, you may start getting a more positive outcome by expecting to be accepted. When you’re entering a new social setting, tell yourself, “They’ll like me” or “I’m going to make so many friends.” You just might be surprised at the outcome. If you tend to receive many rejections in a particular area of life, such as in your career or dating life, you may need to examine your actions to see how you can improve. Think about it: you will never catch a fish if you’re using the wrong bait. For instance, if you are applying for jobs that demand gregariousness and you’re shy, you may not impress the interviewer. Switch tactics and search for a similar job in which it doesn’t matter so much how outgoing you are. You may just get the position. If you interact with people who reject you, criticize you, or put you down on a regular basis, you should consider distancing yourself from those people. Establish healthy boundaries by letting them know that their behavior is hurtful to you. If the behavior continues, avoid contact with the person if you can.  On the other side of the coin, it is important to respect the boundaries of others. For example, don’t keep asking someone out on a date if they consistently say “no.” Let them know that you respect their decision, and move on. People with rejection sensitivity often have histories of abuse or neglect in childhood. In addition, there are certain mental health conditions like depression and attention deficit hyperactivity disorder (ADHD) that are associated with higher levels of rejection sensitivity. See an experienced psychologist or psychotherapist who can carefully evaluate your history and any other symptoms you might be experiencing.
Find a positive support system. Expect acceptance. Rethink your strategy. Avoid people who consistently reject you. Consult with a mental health provider.
