Self help is the best help
We have all heard the famous proverb “Self-help is the best help”. Self-help means help to one’s own self. It is the habit of standing on one’s own leg with confidence. Man comes into this world with some duties to perform and in the performance of these duties lies the true meaning of life.
Every man should do his own duty alone. A man who relies on himself struggles with obstacles and difficulties and goes on gathering power at every step. And as he advances, difficulties vanish and success crowns his efforts.
Nothing is sweeter than the fruits of our own exertion. Moreover, help from within always brings out our latent faculties and strengthens our character. Man needs most of his own help in order to succeed in the struggle of life. Lives of great men bear the truth of the statement.
A self-reliant person knows to overcome any difficulties of life. He is able to move himself out of any difficult situation or condition. On one hand, he always does his work of his own. On the other hand, he is always ready to help others in need of help. This virtuous quality makes him respectable and praiseworthy.
The secret of their greatness lies in their self-confidence, in the realization of their own strength. It has been rightly said that “Self-help is the best help’.
