Good morning, Mike, and welcome back to SBI! and to the forums.
It's not your first time, so you'll know the well worn advice about following the Action Guide to the letter, and you'll find it's changed quite a bit since you last saw it. In particular, it has more emphasis now on assessing monetisation potential before choosing your niche.
And of course, you'll know to come into the forums whenever you need advice, guidance and to share your progress.
I'd also recommend booking in for Terri David's webinars - if you've struggled to get past the brainstorming side previously, they may help you get over that hump. There are free recordings of previous sessions here
, but I'd sign up for the live ones - it's like having your own coach, one to one, for free!
There's one on March 13th (choosing a niche) and another on 27th (keywords) - you'll find details and sign-up information at this link
Enjoy your journey!
