The problem when you're competing on price is that at one point you can't possibly deliver quality work anymore.
Because the lower you go, the more jobs and things you'd have to take on to keep the boat afloat.
And the more things you'd have to work on at the same time, the lower the quality of your work will be.
And the lower the quality of your work, the less you'd be able to charge.
It's a vicious circle.
A vicious circle where the only people able to win are the people who have access to the cheapest talent possible and are able to scale the fastest.
Which is probably not you.
