When you start at a new company, look at extremely complex code and ask yourself every second line: What the hell? Have I ever wrote code before?

Yes, this is me right now looking at complex PHP code at my new company. I feel dumb.

But if was your code, you'd be a master.

I've been working with the same code for about two years and know all my functions and can change stuff and have live in minutes and think I'm a g.

But if I have to get into someone else's code... 2 days for the same change.
