The man whom heaven helps has friends enough.
Joint undertakings stand a better chance when they benefit both sides.
Men hate the haughty of heart who will not be the friend of every man.
Judge a tree from its fruit, not from its leaves.
Learned we may be with another man's learning: we can only be wise with wisdom of our own: [I hate a sage who is not wise for himself]
Oftener than not the old are uncontrollable; Their tempers make them difficult to deal with.
