Seeing things as they are is vital to the life of a Tai Chi person because those that judge or criticize others sooner or later judge themselves … and it is then that 'problems' begin!
Those that except only "perfection" eventually judge themselves as bad students, or a teacher as a bad teacher.
Sooner or later one or the other become discouraged and quits. Conversely, students who find things easy may judge themselves as 'good', and often develop other ego problems. This is the same thing, the other side of the coin - and it has the same effect.
Someone, sooner or later quits.
No definition of best or worse should ever be made in Tai Chi for it is known that he/she who has the greatest ego has the greatest burden. You should wish this neither on yourself or others.

In Tai Chi you are who you are; that's it!
There is only one of you in the Universe,
Thus everything is individual and unique and, like you,
Cannot be productively compared to anything or anyone else.
