Why do I stay vegan enough though I miss certain foods?

No one has specifically asked me this question (not directly at least) but it kind of is a certain subtext to the vegan experience, so I will answer it.

The answer:
The intellectual and rational refusal to support animal exploitation/suffering/unnecessary_death far outweighs the sensation of satisfying the desire for this "missed" food item or any pleasure that might arise from consuming it.

It's not like I think about this much, though. I don't. It usually just surfaces when I'm around people eating non-vegan food and I would (pre-going-vegan) want to try it or share it, but obviously choose not to. For example, being with friends who are partaking in a cake makes me crave a cake. If the cake was vegan, I would obviously partake, and not think any different of it. So in this situation, it's not the non-vegan-ness of it (meaning, it's not that I find the vegan version inferior), but a matter of convenience and proximity. Of course, there are also foods that don't have quite good enough substitutes to really make me able to say the vegan option isn't inferior (e.g. not sure I've really ever found an adequate cheesecake substitute, yet)... So in a case like that, we go back to the "far outweighs" statement -- it's a very intentional choice to adhere to the philosophy of veganism and sacrifice what may be pleasure in satisfying a craving.
