There is yet another important type of preparation: preparation of the mind. That is, to not do anything suddenly, impulsively. Rather, before doing anything, pay attention and think about whether that action should be done or would it be better to sit it out without doing anything.
In particular one must be extra careful with regard to speech, for the tongue is quick to speak, but too much talk is not good — it is bad for Heaven and it is bad for people. Therefore before uttering anything, one should choose what he wants to say and weigh it carefully; if it is for the sake of a mitzvah or some personal need, then he should say it, but if there is no real need to say it — and all the more so if it might entail forbidden speech — then one should shudder at the thought and guard his mouth and tongue. Let him be like a mute person who cannot open his mouth. The verse in Mishlei states: Salvation is in abundant counsel (Mishlei 24:6), and included in this is that one should seek counsel with his own mind and consult with his Maker.
