Freedom

Belittling is different from criticism. Know the difference of those two.

Never let other people bothered you because of their mocking. Let your self have the freedom from those things. They are not worth it to lend some time. Nothing will happen if you focus on that.

Rather focus on good criticism.Take the criticism as lesson. Grow from it. Learn from all the criticism because they may be useful for your own growth.

Know the difference of the two. It's critical for someone who wants to learn.
