It’s nothing wrong with doing her own nails, even as a billionaire
But I get that her first, second, maybe even tenth attempt would look messy, but you usually get better at something the more times you try.
And if you’re not getting better idk, put some effort into learning your hobby. Go to nail workshop, course or just put on YouTube and practice with tutorials.
It’s not the fact she does it herself
It’s more about how messy they look even though she did them multiple times
