It’s a good idea to have the map before you enter the woods! Don't try to become a coach, an online trainer or monetise content without a roadmap because you'll struggle needlessly, when there are proven strategies you could have implemented right away.
Don't try to build a huge fanbase and truly inspire millions of people without knowing what really works, what business models will sustain you, how to scale and serve well. In order to reach as many people as you deserve, it would be advisable to seek guidance from a marketing/branding expert.
Don't try to get brand deals or work with the big names until you know what the industry is like and how to truly make online marketing work for you 24/7. I think that it’s important for both your loved ones and yourself to get the training you need to win. You deserve it!
