I'm on the way to building my own B2B SAAS business. I code all day, sleep for 3 hours, have no money, and sometimes do a couple of freelancing projects to survive.

My friends are in jobs, earning way more than me. I feel a bit jealous, doubting my abilities.

Am I doing right? Or I'm just a nerd with a potato computer struggling like a dog? Am I even walking on the correct path?

I dunno. Already having potential customers for the SaaS? If it's a good path has much to do with marketing I guess

Trust me bro you're gonna need either connections with high profile individuals (millionaires or 6 figure earners in usd) or you're gonna need 5-6 figures (usd) of cash to burn on marketing.

I learned this the hard way

Even if you build a software that solves cancer NO ONE WILL GIVE A SHIT because no one will know about it without marketing

I agree with @horus, this is the fast way to the tomb. Money won't make you happy there..

you are on a self imposed death march in an attempt to break into a highly volatile, competitive and overly saturated market.

Take care of yourself man, I am not saying to abandon your dreams, but there are ways of making it before you reach these levels of self destruction. I recommend getting a job and working little by little on the product that you want to establish whilst simultaneously networking and expanding your people-list.

Sometimes when you are in a good flow it's ok to take longer coding session. Making 3 hours sleep a night a habit will actually slow you down. Potentially break you down quite fast.

@retoor has the gist of it. Does it have business potential, as in clients lines up? Or at least supported by market research. Running yourself into the ground for nothing is the worst you can do.

If possible you can work with a first client to both build it right and potentially sponsoring the work.

If you have a strong business case you might also get investors or a loan. That will take some pressure off.

We can only give you advice like this z there are weirder cases of people making it the way you do. Perhaps in a years time your friends are jealous at you. Hindsight is the only proof.

@AleCx04 I'm building a software in a high-demand & super competitive market but making it so fucking easy to operate & affordable that newbies who use my software once are never gonna go to big companies.

Doing it for micro & medium-sized business where most of the companies doesn't look around. Building it for the people.

Let see.
