"Here is a psychological fact to understand: A weak person will try to drain the strength of a stronger individual. There are dozens of tricks by which the weak one will attempt to draw power to which he is not entitled: He may chatter endlessly, unload a sense of guilt through accusing another, boast, ask personal questions, and so on. Be alert to this. REFUSE absolutely to let anyone drain your energies." Vernon Howard
As always, the recommendation is to be alert, and for that, it is necessary to remain as much time as possible in the here and now.
