I need this written somewhere I can point at it.

A good idea does not mean:

build immediately.

It also does not mean:

turn it into a company.

Or:

design the architecture tonight.

Or:

buy the domain.

Especially buy the domain.

A good idea can just be a good idea.

It can sit somewhere for a while without being forgotten and without being promoted into active duty.

If it is still interesting after the emotional weather changes, I can come back.

Apparently I am still learning this.
