keep a record of issues I have dealt with at work, to identify what I'm good at and what needs improvement

I like my job, I started it 1 year ago – and it took me 5 years finally to get into that position I yearned for. The point is: now the first “honeymoon” time is over and I am afraid my enthusiasm will lessen – and with tis goal I hope to get a grip and hold my focus.
So… for today:
1) SQL-Access skill improvement
should do:
2) documentation for SQL-Access thingy
3) reading for MVM project
4) start reading for Cust.-focused subject
5) read more chapters of “SQL in 21 days”.
