What everyone said here is super great and I don’t know if this will be helpful but it’s what motivated me:

Anytime I saw a thread or someone talk about their biggest regret about their transition, the most common one I found was not starting HRT as soon as possible. I didn’t want to share that regret as I was already very late figuring out my gender identity and I’m glad I didn’t wait longer.

I paint my nails dark colors. It was scary at first, but I only ever get compliments on them. Black is a pretty acceptable color for guys these days.

Shave your legs/body hair. Shaved legs is one of the best feelings in the world and even though it doesn’t feel like it, literally no one notices.

Use feminine hygiene products. If you don’t already, you won’t believe how much better the scents are. I wish I had let myself try feminine deodorant/body wash years ago. Also, no one will ever notice that either.
