This is very good advice.

Of particular note - if you're solving a consumer or business problem that isn't of itself 'technology' - then almost assuredly your 'implementation' is next to worthless until it's mature.

The entire problem lies in the overall user experience, and the customer development channels.

Technical ability is a nice asset, but in most situations it's just labour, like the ability to use a hammer and saw effectively - it's kind of a commodity.

#1 is good as well, thanks to the author, these are important lessons.
