Well there are two things I have going for me that goes hand in hand.
First I am really good at figuring out how thing works, which is a handy skill in games, but also in my line of work as an electromechanic. Things like seeing patterns, undertanding how things work together and so on.
The other is that I can make almost anything work with what I have available, that being info, people or components.
If something is broke, or not working right, it's a good chance I can fix it or jerry rig something so it works for as long as it has to =)
It may not always look too good, but hey it works.
