How to: Stop producing shit
    1. Produce 10 shit ideas each day
    2. Throw them away
    3. ???
    4. Profit!

TBH I actually agree with these 4 steps, but they're exactly the reason people should continue producing shit. It may not make you rich this time around (it could have the opposite effect) and may not have a huge impact, but there's a basis to the 10,000 hours rule, and you're working off some of those hours (or, in oldschool parlance: you're learning from your mistakes).

The value is in producing ordinary work, but being able to recognize why it's ordinary, and to improve upon your mistakes (in the idea, in the implementation and in the execution) the next time around. Usually, the first time painters pick up a brush, their work is shit; the first time musicians pick up an instrument, their work is shit; same goes for developers. It's not a reason to not pick up the brush - to tell someone to stop sucking and start being awesome isn't really advice. I think that this advice is better:

    Practice, practice, practice.

It's much better to be constantly producing shit (and learning) than just to sit around and consume it, and it's not a case of deciding "oh, hey, maybe this time I'll make something good, just for the sake of it".
