It's very simple.
Create something that's worth talking about.
Do something that most people will never be able to do.
Something that's too much work for most people.
Something that most people are scared of doing.
But most importantly do stuff.
Put it out there.
And be patient.
And keep putting in the work.
Longer than most people would be comfortable with.
That's the only "growth" tactic you need to know...
