Photoshop: Pen tool

Today, i'm gonna tell you about smtg a lot of ppl dont know. I was categorized in this kind of people until only lately. All this while, when using photshop, if i want to make a selection, i marquee tool right? If im lazy then the magic wand tool can select for me. If i'm kinda extra hardworking, i'll use lasso tool. I'll just follow the lines the best that i could, but i wont ever looks like professional's.

Y? Because Professional Use Pen tool. Yes, The thingy that looks like a pen but nobody tells you how to use it.
