Is Photoshop Really Worth It?

Photoshop gets all the praise for being the "best" graphics utility for what it is. It's even been turned into a verb. But I don't understand the praise at all. At all. Every time I try it, it's so unintuitive and stubborn that I give up and use MS Paint, which I actually prefer. Is putting the effort into learning it really worth it? Tell me if it's just because of my noobishness.
I'll take you through my latest five-minute ordeal with this beast. I had to resize and tweak a graphic that contained text and a background. Since it was being resized from a rectangle into a square, cutting and pasting to move words was involved.
So I open the file. No problem. Then I take the contents of the graphic and move it into a new image so I have more canvas space to use. Copy, paste. It pastes nothing. For some reason, the shortcut key of Ctrl+V doesn't work, so I select paste from the Edit dropdown menu. Weird that a very common Windows shortcut won't work in Photoshop even though the shortcut is written next to the menu option.
Next I use the Rectangle Marquee tool and drag it across the text, then move the text--oh--the text isn't moving. Nothing is. Huh? I'm not an expert, but I do know about layers and this thing has one, so it's not like I'm grabbing the wrong layer. Just in case I try to flatten the layers into one, but that option is grayed out for some reason.
I tried a number of things and even had trouble getting the marquee tool to turn off (I guess clicking on another tool isn't enough for Photoshop, I have to reclick the marquee tool and click elsewhere in the photo to get this seemingly useless thing away). I finally moved the text (used MS Paint) and continued in Photoshop. Since there were white parts of the background and the background was just a simple one-color shade, I looked for the Paint tool. Not there. I tried clicking on other tools to use them, but they didn't work. In fact, some did nothing, but there was no dialog box to tell me why.
Finally I gave up and used MS Paint except for resizing the stupid thing.
This might seem like very insignificant complaints, but if they're trying to attract me to buy the product, they've failed. Am I just being a noob and there's a very steep learning curve? Frankly, Paint Shop Pro is a ton easier for me (and remembers settings when I'm doing repeat jobs such as resizing a series of images instead of Photoshop, which makes me rekey all my settings in every time the dialog box comes up). Or is Photoshop really this difficult and stubborn?
