Interfering with a third in the relationship
Generally, you do not like to see your partner with a third person at all. This is a normal thing, and often happens in relationships. This happens because your partner begins to mingle with the third person. You begin to think of that third person as more capable and better than yourself. Seeing your partner with a third person causes you to be positive for them. Such feelings get you closer to them, because you are afraid of losing them. Many times this happens, your relationship becomes stronger. Over time, you should explain yourself, and understand your partner. Everyone loves independence, and you should give your partner a space. If you keep your partner in some kind of bond, then he will start keeping distance from you.
Moving a family member
If your child is weak in studies, and you compare him to someone else. Your child does not like this thing, he thinks himself weak and is not able to speak freely to you. Many times, in the family, you see your brothers and sisters progressing more than themselves, and you also want to be more successful in your life. Although you try your best, it does not happen. For this reason, you start feeling jealous of your siblings and your love and attachment decreases. You should convince your mind, try your best, and also think that you have to work for your own progress.
Do not compare yourself to anyone else
If you start thinking of someone more intelligent and attractive than yourself, then it starts to lower your confidence. Every person has his or her own specialty, and you have to recognize your strengths. Many times it happens that you are not expert in any work, and you start getting upset when you see someone else doing that work well. You do not need to do this at all, because there are different types of people in this world, and everyone has their own specialty. Thinking about these things, you start comparing yourself to other people and it makes you mentally weak.
Encourage yourself
It is always the case that you see someone doing good, doubting your ability. You do not appreciate yourself for what you have. By understanding yourself as common, your working power is reduced. If you do not get appreciation for your work, then you should feel proud of your work and be happy for what you have achieved. Sometimes it is also good to celebrate for your success, because doing so increases your confidence and respect. You should rectify your mistakes and shortcomings by always learning a lesson from jealousy.
