The mid-day sun is too much for most eyes; one is dazzled even with its reflection. Be careful that too broad and high an aim does not paralyze your effort and clog your springs of action.

Be careful with too much joy,
it can make you numb in life.

Be careful, in now a day's love can be too much expensive.

For your own self-respect and sanity, your creative freedom, you have to be careful that you don't rely too much on other people's opinions of what you do because it can stunt and inhibit you.

Every nurse ought to be careful to wash her hands very frequently during the day. If her face, too, so much the better.
