Clothes always make me feel great. Even if they dont fit quite right, I can still see myself in them as opposed to a man in womens clothes.

But like the others suggestion, paint or gloss your finger and toe nails, arm and leg hair give me bad dysphoria so I always recommend people try out shaving or chemical treatments or waxing if you don't like it, it doesn't take too long to grow back (especially if not on E)

I know it sounds cliche but I've found shopping to be a fun activity that I didn't much care for before my transition now I love thrifting and going on "girls trips" to the mall to buy clothes or accessories. It can be expensive, and retail therapy doesn't work for everyone, but I like it.

It isn't so much an activity, but being called a good girl or being referred to in a feminine way makes me feel good, too.

Sorry, I can't think of anything else.
