The future has several names, for the weak , it's the impossible ; for the fainthearted , it's the unknown ; for the thoughtful and valiant , it is the ideal.
The older you grow, the more you will know that doing things is not that easy and that everyone has his own trouble, then the more you will not dare to look down upon somebody casually so as to hurt someone heedlessly. This is neither to cover up something, nor to be hypocritical. But it is because you have known the tolerance and gentleness and tenderly get along well with this world.
