There are no tricks in this game, just different rules that each one of us play by.
To grow a channel organically, there are several key things that if you do, you will be successful.
The most important of all is consistency.
All money does is reduce the learning curve by learning from people who have done it, but while the learning curve is reduced, there's still learning that has to be done.
Whether that is through self trial and error or hiring a consultant who can look over your channel, content and strategy depends on how much of the learning curve you want to lessen.
Look at what others are doing in your niche and copy it, but make it better. This alone with consistency will give you more than a fighting chance.
Good luck!
