There is not anything one should not be ready to tolerate, and there is nobody whom one should not forgive.
Never doubt those whom you trust;
never hate those whom you love;
never cast down those whom you once raise in your estimation.
Wish to make friends with everyone you meet;
make an effort to gain the friendship of those you find difficult;
become indifferent to them only if you cannot succeed in your effort.
Never wish to break the friendship once made.
