If you see a need, try to fill that specific need as simply, as quickly and as cheaply as possible. Don’t be afraid to put out something half-assed in your own mind; it might be the exact thing your customers want. Sometimes your best is too much, sometimes spending too much time refining, rewriting and tweaking to make something your best, might be the exact thing which kills it as a product. Next time, just start. Get it out there. Show off your best version to the world.
