Can you imagine that somebody you cannot keep your eyes off goes to a coffee shop with a very attractive one? How would you feel then? In general, most of people would be jealous in that situation. It is because everybody wants to take an advantage of someone who is special, and even more who is hot. Some people people think this is not good and try to change it. And, it will be better because jealousy might result to frustration or lack of confidence. People should learn where jealousy comes from. Knowing oneself is a key to success. They should not avoid that feeling rather they have to experience it more.
