90% of real-world programs are database frontends, held by duct tape.

Most of programming is really just taking data from place A, transforming it, and putting it in place B.

Good product

If you can build a product that is so good, people spontaneosly tell their friends about it, you've done 80% of the work you need to be a really successful startup.

The most successful companies you know, you've probably found out about them because a friend of your's said "You have to try this, it's great!".

One important indicator for a product like that is a product that's simple to explain and easy to understand.

If you can't explain in a few words what you do, and some people say "Oh, that's pretty interesting...", it's a mistake, and usually a sign of unclear thinking, or a need that is not big enough.

Solopreneur

You need 3 things:

1. Going all-in on either (outsource the rest):
   • distribution (sales, influencer, content).
   • product (coding, design).
2. Expertise in a technical skill, be it copywriting, design, coding, finance...
3. Leverage, in the forms of code, media or capital. You can't use labor.
