'You can think of goal creep as the test-driven development of a real-life pursuit.'. No!!! Think about it!!! Test-driven development would be to start writing your winning speech before learning to drive!!! Besides, goal creep is a way to get good motivation, but it's usually very bad for design!!! If you wanted to be very good at racing in the first place, you'd have hired the best instructor out there, and you probably wouldn't have taken all the bad habits that you have now, and would probably be a much better driver today!!!
