compare two "project" tasks
[1] assembling a Revell Kit model for a F18 fighter jet
[2] wanting to make scale models of an F18 fighter jet (without knowing that Revell exists)
in [1] you are given (actually - you pay $19 for) a shrink wrapped box with all of the parts, instructions, and a very tight objective. Only your time and skills are required.
in [2] you have a image of a real F18 fighter model in your head and that is that.
in [1] there is a "parts list", "instructions" and plastic & glue given to you - what you don't see is all of the molds, design, tests, marketing, finance, logistics that had to take place to get that model to you.
in [2] - you have the full range of options - from pretending that nobody has ever thought of this before and hand carving and painting 1 model for yourself (and then your brother wants one - ok, 2 models - and then ....)
- to -
creating a whole new industry (you thought) for making scale models - including F18's.
- to -
do a Google search for F18 models and go back to [1]
Q: so why do so many people do [2] for their favourite project? i.e. "we'll cross that bridge of design, supply, finance, hire, manufacture, market, ship, refund, layoff, get sued, ...." when we come to it. And the next one, and the next one - and so on until - oh rats - we're stuck in the middle of a bridge and we're out of gas.
