Why am I not proud of myself?

I set myself a challenge that I would go vegan for 30 days. I am on day 16. No meat, fish or dairy has touched my mouth. At least not that I am aware of!

Going vegan was more for health issues and self-discipline. I wanted to see how strong I was mentally. I’m genuinely shocked I’ve made it this far.

Though, I don’t feel like I have achieved or done anything outstanding. I feel like anyone could do this. Am I right or maybe being too harsh on myself? For someone who is 220lbs I never thought I could do this. When I complete this I am going to start a beginners running app. I want to get into shape.
