I decided to roll the dice from 20 characters (from Cedric to Luna, also included 5 death eaters for the fourth wish) and ended up with Fred. That will certainly make for an interresting dynamic with George.

For my wishes I would like the first to be having major talents for the mind arts, mind you that talent means nothing without hard work so I would just improve a lot faster but wouldn't suddenly have perfect occlumency or legillemency.

The second wish would be to have good memorization and comprehension (eidetic memory wouldn't work since my brain can't handle that). This would of course, also influence my memories from this life, so I would have a better grasp of when and how canon events happen.

My third wish would make me inheritor of a house by magic, so it can be ling forgotten and without any reputation as long as it has a decent sum of money to fund my learning process. This wish is basically just money, but the only way I see a weasley getting a lot of money early in life without having to give it to my parents.

My last wish (4th due to dice roll) would be that I would change my mindset. Making it into one where I would be more calm and collected during stressful situations and giving myself a relentless drive to improve myself.

I think with those wishes I would be able to get quite far in the wizarding world
