We discussed earlier that those who trust in G-d constantly have peace of mind.

This does not mean we should sit back and refrain from taking action for our welfare. Rather, it means that even when you do take action, you realize that the ultimate outcome is up to the Almighty. Hence you will have peace of mind regardless of the outcome.

Moreover, while you will take action, you will not panic. You will do what is necessary under the circumstances, but will not act out of anxiety and "desperation."
