Hi Paulo! Hold on to your visions no matter what comes your way. When you love what you do you will keep failing forward.
Success is just a substop towards the next goal. It never ends. By doing what you love you create meaning and that's the greatest value. -my own definition.
Money is a secondary process. It takes time and management, planning. Probably comes at the later part when a product or service is getting ready.
But it has to be planned from the start. All pieces of the puzzle are just as important that makes up the complete picture.
I find the law of attraction and the creative process extremely important in unison.

The greater the vision the harder one must work.
Alone or with a team, and that takes money and recources (most single developers don't can afford).
My grandmother used to say "With small means you'll come a long way". I have added "With knowledge, project and extermely hard work you'll get even farther".
Elon Musk proved that. I've been watching many documentaries about Steve Jobs, Elon Musk, Bill Gates, Ingvar Kamprad, Oprah Winfrey.
Hard work seems to be the key to success. Still I don't make any money and I might never be able to do so, but I still love what I do and that's my greatest value.
All the best,
Roger
