It happens that out of stupidity or because of strong emotions, a person acts to the detriment of himself. Learning to control the situation and in any position to see your own benefit is possible if you work on yourself.
Think about yourself
To learn to see your own benefits in everything, you need to understand what you want, what you need. Otherwise, it will be difficult for you to determine your goals and act in accordance with them. Listen to yourself, imagine your ideal future, or remember what you loved in your childhood, when your actions were practically not influenced by public opinion.
By the way, you should think less about what others will think about you. Of course, this does not mean that you can commit dishonest acts and go over the heads for your own benefit. But when you take a step, the thought of a possible condemnation of your actions by other members of society interferes with you, you need to objectively assess the situation without looking at those around you. If you are not doing anything wrong to anyone, why not stop being embarrassed and act in your own way.
Learn to defend your point of view. Some people know what is best for them, and would be happy to turn the situation to their advantage, but they cannot resist others. Know how to argue with argument, respond to objections of the interlocutor. Work out a strategy in advance that will help you win the discussion. Learn to cite facts that will convince other people that you are right.
