Favourite and least favourite skills to build?

@Evalyn326 There are many ways to build the logic skill, some just aren't very obvious, others are impractical because of the ridiculous sizes of the objects required. If you're tired of playing chess, try using the telescope, the microscope, the science equpiment from GTW, or drawing mathematical diagrams at the easel (yes, that actually builds logic, not painting, but you have to be focused for the option to appear).
