ears???? not brain ?

you need a combination of :
- Aptitude to learn how to learn about DR. read that a few times and it will make sense!
- Patience and ability to think first and act when you are pretty sure you know what those actions will do.
- Experience. Experience alone can dictate a path when all other influences lead elsewhere.
- help. Without help from our peers, I think a lot of jobs wouldn't be successful. Sometimes the comradery-ship alone will keep us going and interested in a job long enough to solve, even if the other people didn't technically provide info.
- Motivation. how many jobs do you have sitting in a box where you have pulled it to bits, but the motivation is not there to hook up that logic analyser or JTAG?
- to be able to pull resources together, not just expect answers from one or 2 sources

a combination of a lot of things will separate the good DR person to a GURU.
IMHO

yeah true. from my side i would like to say everything is important by its role.everything...
lets suppose if you are a good Dr and having everything like pc3k,firmwares,soldering iron,station,but just don't have a torx screw driver and patient drive came with burnt card and screw is slipped at this point you will know the value of a screw driver although you have a scientific lab and you are a good ,trained ,expert.... but fail. so we can say this a combination of things and resources make solution.
