"The only way to learn mathematics is to do mathematics." Paul R. Halmos.
On a scale from $1$ to $10$, with $1$ being the worst and $10$ being the best, I'm about $-i$.
I'm a postgraduate research student in combinatorial group theory at the University of Essex and I absolutely LOVE Mathematics. My supervisor is Prof. Gerald Williams.
I was a graduate teaching assistant (GTA) in real analysis during the Autumn term of 2018. (My name is in the complete notes for the module as such (but they're only available to students) and my profile on the Essex website used to list GTA as one of my rôles in the department (but currently doesn't give my specific modules, past or present)).
You can find a copy of my award-winning MMath dissertation on inverse semigroups and inductive groupoids here. My supervisor was Prof. Victoria Gould at The University of York.

Here's an idea for a future question of mine. This link is so I can find it again.
This answers the question above.
I once mistook involutions for idempotents. See the fifth revision of this answer. Oh, the shame!
