It's crazy how nobody really talks about this.

An idea pops into your head. You validate it. Maybe a few people tell you it's a good idea. Next thing you know, you're three weeks deep into building the next X (formerly Twitter).

There's just one small problem:

You're not building for users. You're building for yourself.

The way developers see products is completely different from the way users see them.

A developer sees pixels, color gradients, load times, request speeds, database queries, security, and architecture.

The user sees one thing:

An app.

That's it.

Most users don't care that your font size is off by 2px. They don't care whether you're using React, Vue, Laravel, Next.js, PostgreSQL, MongoDB, or whatever new framework launched last week.

What they care about is simple:

Can I use this thing without getting frustrated?

That's the real question.

Think about the products you use every day. Why do they have millions of users?

It isn't because the UI is beautiful.

It isn't because the architecture is perfect.

It's because they're usable.

Can users understand your product without watching a tutorial?

Can they complete important actions without getting confused?

Can they find what they're looking for without clicking through five different screens?

If the answer is no, then you don't have a technical problem.

You have a product problem.

And product problems kill side projects much faster than technical ones.

The second reason: developers love over-complicating things.

A lot of developers struggle with this, especially when building side projects.

A simple note-taking application somehow becomes:

• AI-powered
• Real-time
• Multi-tenant
• Offline-first
• Blockchain-enabled

All before a single user has written their first note.

A notes app doesn't need AI.

It needs to let users:

• Create notes
• Save notes
• View notes
• Delete notes

That's it.

There's a difference between building the right thing and just building things.

The hack?

KISS.

Keep It Simple, Stupid.

(Or Keep It Short and Simple if you're feeling polite.)

The principle is the same.

Your application should perform its primary task exceptionally well before you start adding features nobody asked for.

The more complexity you introduce, the more opportunities you create for things to break.

Build with KISS in mind and thank me later.

The third reason nobody talks about: no deployment plan.

This one hurts.

You spend months building.

Next.js for the frontend.

Laravel for the backend.

PostgreSQL for the database.

Redis for caching.

Docker because everyone on YouTube says you should learn Docker.

Everything sounds cool until it's time to deploy.

Now you're trying to figure out hosting, environment variables, SSL certificates, databases, storage, monitoring, backups, and why your frontend suddenly can't talk to your backend.

This is where many side projects quietly die.

Not because the code was bad.

Because nobody thought about operations.

Before writing your first line of code, ask yourself:

How is this thing actually going to run?

How will the services communicate?

How will updates be deployed?

How will users access it?

How will I keep it online when something breaks?

Your goal isn't to build something that works on your machine.

Your goal is to build something users can depend on.

Those are two very different things.

Final thoughts

Most side projects don't die because of bad code.

They die because nobody wanted to use them.

They die because they're overengineered.

They die because the developer spent more time choosing technologies than understanding users.

And sometimes they die because nobody thought about what happens after the code is finished.

The irony is that writing the code is often the easiest part.

Building something people actually use?

That's the hard part.
