How to be pretty w/ executive dysfunction

I'm not pretty. People who say 'looks don't matter' are living in a fantasy land. It's been proven that you're chances of success are highly based on how you look and how much people like you.

I've seen so many beautiful people talk about consistency with their beauty and for me consistency is something unachievable.

I need some tips on how to start becoming beautiful while also working around executive dysfunction.

Edit: Thanks for the advice

It's mainly just dealing with hygiene and executive dysfunction.
