Just okay and suddenly getting better?

Just okay and suddenly getting better?

Wife has always just been okay and some things and recently she just got better less worrying about being perfect.

Has she been watching me making a point to improve or has she just done it enough times to be better and not worry she is doing it perfect?

Nothing has really changed at home or work which has me surprised by this change.

What would have changed to make her better? What would she have done to just get better so fast?
