Flying Diary
I also kept a diary about every lesson during my training last year, and still do now. Every flight I write a few pages about what happened, what went well, what I learned, what didn't go well. I also put a few notes about wind and runway in use etc., how I felt, anything new. Its a great way to consolidate your experience to write things down, and as Thing says, it will be nice to look back on in years to come (if I can read my hand writing that is...)
