Tolerance of other people's views, actions, lifestyle is a quality that is not given from birth. If it is not laid down by family education from early childhood, you, and the people around you, will have a hard time. Nevertheless, tolerance can be developed independently; for this, a high level of self-control and the ability to find harmony in one's own soul are needed.

one
It is important to find out the reasons for your own intolerance. In the desire to criticize and condemn, people are often driven by the idea of their own way of thinking and acting as the only right and possible. Some “overstate the bar” and refuse to accept anything that does not meet their high standards. Self-esteem also makes it difficult to accept others as they are. Try to understand yourself and understand what exactly prevents you from accepting the existence of views that are different from yours.

Look at the people around you, try to understand the motives of their actions. Perhaps they will become clearer and closer to you after you try on each person’s life situation for yourself. The ability to empathize and sympathize will help you with this. Be condescending to others - it is unlikely that other people's words and deeds have a serious impact on your life, and therefore it makes no sense to spend emotional resources on them. Not always even the most unpleasant actions are intended to harm you, and you can treat a lot with a certain amount of humor.

The main components of tolerance are the ability to accept and forgive, restraint, flexibility of behavior. Be friendly to others, look for something good in those who cause you irritation and rejection. Remember how easy it is to offend or push away forever with just one word, even when others forget about it. Learn to restrain your own emotional reactions, express your opinion as correctly as possible.

Take for granted that the world is much more complex and wider than you think, and everyone has the right to their own opinion. This does not oblige you to maintain someone else's point of view, even out of politeness, but to respect it is the duty of any civilized person. Think of other people first of all as equals, having the same rights as you.
