If we relax out of painful emotions we find good judgment and happy instincts behind them.

If we relax so that pleasant emotions can pass over our nerves they leave a deposit of happy sensation behind, which only adds to the store that Nature has provided for us.
To sum up: The two main reasons why women are nervous are that they do not take intelligent care of their bodies, and that they do not govern their emotions; but back of these reasons is the fact that they want their own way altogether too much.

Even if a woman's own way is right, she has no business to push for it selfishly.

If any woman thinks, "I could take intelligent care of my own body if I did not have to work so hard, or have this or that interference," let her go to work with her mind well armed to do what she can, and she will soon find that there are many ways in which she can improve in the normal care of her body, in spite of all the work and all the interferences.
To adapt an old saying, the women who are overworked and clogged with real interferences should aim to be healthy; and, if they cannot be healthy, then they should be as healthy as they can..
