I want to shoot myself in the foot

I had one of the most enlightening conversation yesterday. I was talking to the professor whom I am interested to have as my thesis adviser. We talked so much and by gosh, she gave me so many pointers that I've never thought of before e.g. variables, comparison, research methods, steps, possible approaches....

Later I was trying to write down what we've discussed and guess what?

I should've taken out my notebook when I was talking to her and write everything down.

Brilliant.
