The ruling power within, when it is in its natural state, is so related to outer circumstances that it easily changes to accord with what can be done and what is given it to do.

You are making an inopportune rejection of what Nature has given you today, if all your mind is set on what men will say of you tomorrow.

Remember that to change your mind and follow him who sets you right is to be none the less free than you were before.
