I wouldn't say I'm the most knowledgeable when it comes to fixing things, but in an era of information, I try to fix what I can (even if it's changing a couple of filters or lights in my car).
My favorite hobby, Subbuteo, requires me to assure my 11 figures are equally balanced and at times, painted to my favorite colors! The weight and stability enhances my performance so I pay close attention to it.
Saving money and learning something new, will always grab my attention!!
