Bike build....
my automotive instructor used to tell me to formulate an idea of what I think I want and tone it down a notch or two and that will most likely be the sweet spot that makes me the happiest.
Of course I was much younger when he told me this but he said too often what people think they want is somewhat a pie in the sky. So toned down a notch or two will most often be more practical and affordable and win in the long run.
I have to say that the few time I listened to his advice it rang true....for me anyway.
Now that I am getting older and closer to 30, I think some of the ideas I had in my youth were really dumb. LOL
