Learning Taiji is to solve a set of contradictions.
Neither over-extended, nor deficient.
Anything that exists is the resolution of a contradiction. Therefore, when you see a contradiction in a matter, you have not resolved the issue. When you have, you will not see the contradiction any more.
In taiji, you must reach a stage when you create movements without moving; you don’t push but your opponent is pushed out; etc. When you still cannot do this, you are still not at the level yet.
