As of today, I'm a certified flight instructor!
What a long time this has been coming. So much work and preparation has been put into this one day. I don't even feel completely comfortable with everything yet, and I'm still learning a lot every day.
For the first time in my life, I started something, and I finished it. I still have more work to do before I'm employed, but I'm a whole hell of a lot closer today.
I'm so incredibly ecstatic!
