I love learning on my own how things work... I spend hours taking things apart and putting them back together again, more often than not, with some modifications or improvements both cosmetically and functionally.
Right now, I can probably fix anything mechanical (electronics require a bit more work but is not that hard), I've disassembled TV's, radios, car stereo systems, CD players, DVD players, phones, amplifiers, musical instruments, computer monitors, computers, laptops, PDAs, cellphones, washing machines, watches (one of the more difficult jobs) and stripped down at least two cars on my own... so sue me, I was bored.

for the past few years after I left college behind, I've fashioned myself as someone who is absolutely sure of what he's doing, or at least make it look that way, both with regards to my professional and personal life, Its been a while since I've felt unsure of anything, usually I know exactly what to do or am willing to find some way, any way, to get things done, whether its trying to solve problems (usually for other people, though) finding the right solution (or the safest), and just basically trying to help out.
I know its not my place to try and fix everything, but it just feels weird to be so helpless
