As you can prove to yourself by rereading the parent comment of mine, I have stated not that “good ideas and inspiration are not a product of routine”, but that “good ideas and inspiration do not come up routinely”. To further explain my thoughts, let me add that one need not be inspired or have a good idea to train themselves (
training is what the kind of routine we're talking about ultimately is), but need be wishing to train and have
some idea, which need not be good.
It is a fine method of developing one's art/science/etc... skills to regularly practise, but not a fine method when it comes to startups and founding companies, think I; for such things happen to have consumers, people who may be favouring the product and incorporating it to their daily lives, which will be disrupted when the founder loses their interest in that product and proceeds to the next month's startup.
They may have had a goal of building 12 web sites in 12 months, or 12 blog posts in 12 days, but this person chose to launch 12 startups each month, and launch those to press. Launching companies regularly is dissimilar to painting regularly. (TBH, I did not double check if this serial founder is referring to some ordinary web application as startup)
