How to overcome low self-esteem? First you need not to condemn yourself. Everyone struggles with the issues of self esteem but the difference is how they express it and to what extent. Proper self esteem is a human being appreciating their God-given value irrespective of what they have or lack, what they know or don’t and independent of anything that they have laid claim to after leaving their mother’s womb.
Let us look at it this way: those who despise their fellows and think that they are better than others who don’t have as much money or education and as they do is suffering from low self esteem called pride and arrogance. They are not any better (or worse) than those who feel inferior to other people because they lack this or that thing that others have. The difference between these two extremes is just how it is expressed.
So where is the way out? The only known cure is for you and any other person to accept and celebrate the beauty of your human-ity, and not “have-anity”. Remember, you brought nothing into this world and you will definitely carry nothing away. Keep your expectations and focus on who you are, and not what you have or don’t have.
