Our personal ascents and descents should not affect external dissemination. As organizers, instructors, and teachers, we always have to behave consistently with the outside public. People should not feel that you are going through ups and downs. You must maintain contact with them every day, providing them with everything necessary, and your inner states are your personal matters and nothing more.
It is desirable to be like that in relations with friends. Friends have to see you in constantly high spirits, inspired by the importance of the goal, joyful, and to feel your support. And for that, you sometimes you really have to play at that.
At most, you can complain that you are a little tired today and can find some physical reasons, but don’t let them suspect that the reason for your bad mood is internal. Externally, you have to appear cheerful, striving only forward, showing everyone an example.
From the moment that you could have set an example for others and did not do so, all their negative states are immediately credited to your account! It is like communicating vessels. If you cannot fill them, that’s it! Their desires that you did not want to fulfill are transferred to you and fall on you as an additional burden. It is important to be aware of that.
