"What works, what doesn't" - do you ever do this?

[MPLouis]

One of the best things I've learned to do in my football betting is ask myself "What worked, what didn't" for a given day of betting. I write a short report for myself. It takes a little time (between 30 and 60 minutes I think). I try not to go into too much detail, but concentrate on some of the main bets, with the aim of improving my betting. So I look for areas where I am winning or losing. Just wondered if anyone else does this, and how it works for you?

Re: "What works, what doesn't" - do you ever do this? Always good to learn from one's mistakes ;) But rather that writing "reports" to yourself (up to 60 minutes :loon), why not just keep an Excel database of your bets and results, and then you can interrogate the data to highlight your strengths and weaknesses?
