when I was 17 (13 years ago) I was doing my A-Levels in computers and we had to build a booking system using excel. that's when I discovered VBA, I learnt a lot and it made the project so much easier to do and with that I wrote my first calendar which was 365 lines of code. one line for each day of the year. it wasn't until I completed the project and going over some of the code it hit me, I turned 365 lines into 4! I was so pleased with myself. one of my best moments of programming.
