If there was anyone who helped me become a better programmer, it was my first tyrant boss, who was a complete asshole. I adopted his practices: write out what you want your program to do. What is its purpose? What does it do? How does it operate? Who will use it? Why? What will they pay for it? What will it look like? What pages will it have? Does it need these pages? And a bunch of other questions. It really helps to save a ton of time and keep you on focus.
