any advice for how to write an effective annual self-evaluation?

I feel like I'm always doing my best to contribute to the team and handles all task assigned smoothly but looking at the daily notes of what I've done since last year they all seem so trivial ==''

Well, you've almost written exactly what you could write.

It's all so trivial, indeed, but do the people who read your report see that? Usually: no. Most people need to have spelled out for them what is trivial for you.

The other way around is true too. For example: read this comment again.
