The first step is to have a hypothesis.
The second step is about realizing that it's just an assumption and probably not the reality.
The third step is about testing your assumptions on the market to see whether or not they hold true.
Unfortunately, they almost never hold true...
And then the fourth step is about adapting your assumptions to your results and to test them again.
The fifth step is to repeat steps 1 - 4 until your assumptions are validated.
The sixth step is about not getting frustrated and not giving up while you go through steps 1-5.
Most people never make it past the sixth step.
Don't be one of them...
