I don’t believe I’d require a lot of magic. Sure, being powerful would be fun, but even magic has its limits.
I imagine I’d use it primarily for cleaning and housework (Oh the possibilities – tidying an area with a glance) or finding and tracking things. You know how you spend ages looking for something and then find it in the first place you looked? I just spent maybe an hour looking for my debit card so I could make an online payment. First place I looked was my wallet… Last place I looked was my wallet, and I just hadn’t noticed it buried beneath a sushi rewards card and some old receipts.
That, I believe, is called Murphy’s Law, and Murphy hates the general populace. Therefore, I’d primarily use my powers to never have an eye-rolling, embarrassed laugh of “Oh, Murphy’s Law” moment again. With magic I could just retrace my steps so perfectly that I would find it, and in less than a minute. I was going to say a summoning charm or something, but that’s just borrowing from Harry Potter.
I would also make it so that the tool people use on Facebook to invite their friends to ‘like’ pages would be obsolete. It’s annoying being invited to ‘like’ something – I have told the culprit of this annoyance more than once, if I want to ‘like’ something I’m more than capable, certainly intelligent enough to figure it out for myself.
Then I’d make it so no-one else had to put up with Murphy or the invites, making the world much more efficient.
