Zawinski's law of software envelopment

Zawinski's Law of Software Envelopment is a rule that states software will always grow to take up more of your computer's memory and storage space than you expect it to. It's like when you buy yourself a new pair of jeans, you have to get a bigger size because it ends up shrinking when you wash it. The same thing happens with software - the more you use it, the bigger it gets, taking up more memory and hard drive space than when you first installed it.
