I'd be lying if I said I didn't have any or only a few. I have several, but ironically, not enough to forget them, so I'll only mention three that I've had in mind for a long time.
When I got my first pet, when I went to pick it up, it was lovely to look at it for the first time. Its beautiful eyes, its fur, its size—everything was beautiful, just like when I picked up its "wife"

and then the new babies were born (everything was beautiful).
When I finished a marathon, I never imagined I would be able to do it, and because I was tired, I couldn't enjoy it. But today I see it as something great, something that made me feel very happy.
When I entered middle school, at times I felt it was difficult, I didn't trust myself, I had very low self-esteem, and I felt like my family didn't fully believe in me.
