This question will always be asked: how much time should I devote to this?
There is no true answer to this. Instead, what I encourage you to do is go through the whole course, see the framework as a whole and understand what you need to do to make it work.
From there you can decide how much time you want to devote to things.
What's great about building a BRE is that the steps are very clear and repeatable.
You can decide that the first Saturday of each month will be devoted to finding new content ideas while Wednesdays are for writing.
It's going to be up to you.
The more time you can spend writing content that people want and getting that content out there, then the better your chances of getting traffic quicker.
If you want to take things slow due to time constraints then that's fine as well.
When I say it's possible to get to $1,000/mo in 6 months, I don't mean it applies to every single person. You might find that you wrote 10 posts and they are getting you to 100,00 pageviews while others might need 30-50 posts.
To sum it up, you have to decide on your own how much time and energy you want to devote to this process.
I'm a firm believer in momentum when it comes to your business. Successful businesses run on momentum.
When you have forward momentum going for you then it's hard to stop.
If you follow everything outlined in this course and keep pushing forward then you will see positive things happen for you.
