convinced

The more Matthew thought about the matter the more he was convinced that Anne never had been dressed like the other girls--never since she had come to Green Gables.

There would be other springs, but if she did not succeed in passing the Entrance, Anne felt convinced that she would never recover sufficiently to enjoy them.

Elizabeth listened in silence, but was not convinced: their behaviour at the assembly had not been calculated to please in general; and with more quickness of observation and less pliancy of temper than her sister, and with a judgment, too, unassailed by any attention to herself, she was very little disposed to approve them.

By all that I have ever read, I am convinced that it is very common indeed; that human nature is particularly prone to it, and that there are very few of us who do not cherish a feeling of self-complacency on the score of some quality or other, real or imaginary.
