How to write bug-free code

Listen hard and listen fast. Listen once; I won't repeat myself...

While writing code, if you ever say to yourself:

• Oh! but this will hardly ever happen OR


• The user will never do this OR


• What are the odds of this happening??

Please please please go ahead and write some code and comments to handle that situation. You can't ever be too careful.
