Do not wait until the time comes, but work on it now; that is, work on your own consciousness concerning it, and in the present tense. Do not try, as it were, to throw your treatment forward. This cannot be done successfully. The event may be a future one, but the very fact that you are thinking of it at all means that it is present in consciousness; and as the thought is a present one, it can and must be dealt with in the present tense.
