I'd generally agree with that, but I was recently at an excellent qi gong workshop taught by Yang Yang, who told the students to do qi gong with an attitude of "I am a master"

Note that "I am a master" is not falsifiable, unless you also have some idea of what being a master consists of. This isn't a problem if you believe (for example) that a master is someone who is always learning and improving, and who makes mistakes.

Of course, at that point, you are right back to having a capability belief. ;-)
