High-Quality content and patience. Everyone says the same but 99.9999999% of people forget the patience or think patience = 3 weeks.
I'm still new here myself but I can see what needs to be done. If you consistently post good content (every 1 or 2 days) that people enjoy within 6 - 12 months you will be golden. I can't see how this strategy can fail.
We all have an equal opportunity just from the contribution aspect regardless of where you live in the world.
