There's nothing like being knee-deep in some spells with your homies. It makes you feel like one powerful wizard. That's a fun thing about DnD, once you become fluent in the spells and cantrips, you start to feel like an actual wizard. Your knowledge and know-how are affecting the game in supernatural ways. If only it were like this in real life.
You could cast a spell to skip ahead in time when you were about to go into a work meeting. You could cast a healing spell on your paper cut. You could cast fireball on… your enemies. I suppose if you got really into herbal remedies and the like, you might start to feel like a real-life warlock, witch, or wizard. (Honestly, I'm still not clear on the difference between the three, feel free to educate in the comments). But for now, we'll just have to settle for DnD memes to make us feel magical.
