You may not really know how to go about tackling your dream but that kind of attitude is an extremely good start and will most likely serve you very well in achieving your ambitions.
Yes I know a Concorde pilot, in fact he took me flying once (in an Arrow). He never really talked about flying the Concorde, but I do remember him wearing little wrist bands as he claimed that light aircraft could make him feel sick. I think he's a skipper on 737's now.
