I can also read it like this, though:

> The largest problem d̶e̶v̶e̶l̶o̶p̶e̶r̶s̶ people have with b̶o̶o̶t̶s̶t̶r̶a̶p̶p̶i̶n̶g̶ ̶a̶ ̶p̶r̶o̶j̶e̶c̶t̶ doing their own thing is that they focus way too much on b̶u̶i̶l̶d̶i̶n̶g̶ what they like to do.

Isn't that the whole point of doing your own thing, though? If you really want to make money (desperately) the strategy would certainly change, but a lot of developers are really just pursuing a hobby or side project with a (probably unrealistic) dream of striking gold.
