a couple of suggstions:
- be bold about what you have achieved this year. This is not the moment to be modest
- pick up one or/no more than 2 areas that you see as opporunity to improve or work on - no one is perfect
- if you feel strong about it, like what you did, ask for a raise directly.
- be prepared to be rejected or to have discussions to justify
- worst thing is to over-think about this: should I do this or should not. Be reasonable but assertive with your idea.
Good luck.
