Heeeey, welcome to The Club! Congrats
Indeed, now that you know you can and how, more are on their way.
2 RCs, that's great. Looking at hands and counting fingers is my favorite one, because it's just so much fun to count more than 5 fingers, lol. It allways gets me laughing.
There is something very easy you can do to help you remember things you want to do in your lucid.
1. Write your goal into your dream journal
2. Daydream about it
3. Draw a picture of it
and the really weird one:
4. Practice it in waking life. During day, stand up in your room and pretend you just got lucid. Now go through the motions of your goal.
I practiced yelling commands and stabilizing. Close your windows, lol, and yell out a command "clarity now", "stabilize now"...
Touch your clothes, your feet, arms, the ground, smell the air...
Then let's say you want to throw fireballs - pretend you just made a fireball in your hand and throw it! It may sound funny, but it does work.
Also, raising your daytime awareness helps you carry more memory and awareness into your dream. Pay attention to details of your day as you go through it.
Good luck and happy dreams
