I'm vegan now, previously vegetarian. But before this I was in exactly the same position as you describe. It's the first time that I'm actually hearing of someone who admits there can be an inconsistency between your own behaviour and your values.

Depending on what it is, sticking to your values is hard and requires changing your behaviour and habits. Your environment matters a lot. For me it was easy to switch to a vegetarian diet because my partner loves experimenting with cooking and collecting recipes. For many it won't be this simple.

I used to think it would be easy for people generally to admit that it's pretty unlikely that they're sticking to all of their values, but apparently it's not. I think it's impressive how you're managing not to let personal pride determine your opinion on this!
