Are you jealous of others because of something they have or can do?

Let's be honest,  when we envy what others  have or can do, it's usually because we ourselves lack or are lacking in those things. At least, that's what we think to ourselves, or unconsciously. If you envy the wealth of others, you probably don't have enough money to spend. (You might be middle class or wealthy, but you still have an unsatisfied need to spend money.) If you envy the beauty of others, you probably feel like you're not pretty enough. (Maybe many people think you're beautiful, but you still feel like you're not perfect.)

If you envy Messi's soccer skills,  you must be dissatisfied with your own soccer skills. (Maybe you're already on a school team or even a state team.) You'll find that the answer to this question varies from person to person, but they all follow the previous statement: What you envy others for what they have or can do is what you lack or lack.
Please note here: lack or absence is a relative term, a personal experience, a subjective judgment. It is not an absolute concept, nor is it an objective standard.

So, what can you do to overcome the envyness is the ability to heal oneself.

If you can't solve a problem, practice more. If you are criticized, just criticize. You are not a star and no one pays attention to you every day.

If a conflict arises, find a way to resolve it. If you can't resolve it, don't force yourself.
You need to create your own script. Before that, you don’t have that many roles, so there is no need to add more roles to yourself.

When you have less inner constraints, you will feel that every day is fulfilling even if it is hard.

Why do you get overly concerned and blame yourself over the smallest things?

The first is because of secular views, and the second is because you lack the ability to heal yourself.

You have no way to get out of your bad mood, and no way to heal your scars in time. You choose the cruelest way: keep exposing your scars. They would have healed slowly over time, but you insist on stimulating them again and again, making them bloody and bruised. Some people cannot even heal.

If a person wants to achieve real growth and grow away from the interference of negative external voices, a real and effective way is to cut off all the links that bind you and focus on the present.

When you realize that you cannot rely on your parents, relatives, or friends for help, and that you can only rely on yourself for everything, then you will harden your heart and work hard.

Sometimes, cutting off one's retreat is to move forward faster.

When you have no expectations of others, you will not be disturbed by other people's opinions, and you will not let other people's thoughts interfere with you too much.

If you do something wrong, you will correct it promptly without blaming yourself too much.

If you are criticized by the teacher, you will not be too sad, but will try to correct your mistakes if there are any and encourage yourself if there are none .

When conflicts arise with parents, I will not change my mind easily. I will continue to take one step at a time and do what I should do steadily.

All your focus is on yourself, and all your emotions will serve yourself.

The world will not treat you well because of your changes for the time being. It will still bring you all kinds of troubles, but your focus is on yourself.

When you are really busy, you have no time to care about what others think of you.
"I am good, I am wonderful, I deserve all good things, and I will live the life I want to live."

This is a kind of self-confidence, you must have the courage to live a good life.
