There's no doubting it. I'm nothing but an idiot. I just can't seem to properly figure anything out without a guide anymore...I feel useless and stupid. I'm supposed to be GOOD at logic puzzles! Why am I suddenly the stupidest person on the planet?!
Don't be so hard on yourself my friend! It might just be you give up too easily. In any case, you can get better. Stay positive. Your mind is not stagnet, your brain is a learning network...it is designed to get smarter.
It's not that.....I literally failed to figure out I could get between a portal removing wall by placing two portals on both sides...it's simple logic..
Video games are not inherently logical though. You may have thought that idea wasn't possible to do (a state of doubt), based on other aspects of the game that didn't work the way you thought. Video games can really mess with you...and not in a good way. So, don't take it too hard.
