Electricity
I was interested in wires since childhood and that made me learn all I could about electricity. I remember learning from an excellent professional that used to work with my father, named Felipe, may this be a small tribute to him. In school, my then physics teacher and now friend, Manuel Narváez fed my interest and made me learn some theory.
Thanks to all this I have been able to work easily with excellent electricians (my University colleague and friend Rafael Navarro comes to my mind) that have taught and helped me a lot with job related and personal projects.
And, as result, now I have started my biggest project: redesign and install myself all of my home electrical wiring.
Plumbing
This was another result of my learning inclinations, and my grandma's love for reforms :-). Guillermo, a complete professional that executed her projects while I was in my teens, took the time to teach me while working, and it seems he was as good at teaching as he was at doing his job.
I confess that I have not dared to use the soldering lamp, but I like changing pipes, installing taps or fixing toilet flushes. Though, I admit that I really get mad when I have to redo something several times because of dripping joints.
Tools
All these interests require adequate tools, and I have a good collection of them, new and old. I even have a wooden spirit level, which is almost a century old, and belonged to my great grand father.
You need the right tools for each job if you want things done right.
