It is easy for a person who feels less intelligent than others to have low self-esteem. This is unnecessary. While there are many advantages in having intelligence (for Torah study and other pragmatic reasons), when it comes to basic value of a person, intelligence is not a key factor. You can be righteous regardless of your intellectual ability. Similarly, intelligence is not a decisive factor in whether or not a person will be happy in life.
Since you can be both righteous and happy no matter what your level of intelligence, there is no necessity in feeling less of a person if others seem "smarter" than you.
Self-confidence allows you to create goals -- and reach them. It lets you learn from your failures -- and move on to triumphs. It helps you
transform your potential into real achievement. With the help of Rabbi Zelig Pliskin, you will gain that self-confidence.
Rabbi Zelig Pliskin is the author of 25 books with his specialty in mastering happiness and other positive inner resources.
His last 15 books include: "Taking Action", "Happiness", "Kindness", "Courage", "Serenity", "Building Your Self-image" "Conversations with
Yourself" and "Marriage." These books are available at: Artscroll.com.
