Rob,
This IS a big Decision. I wish you Great SUCCESS.
Several people I know have accidentally stumbled upon or got started with the bizopp market simply because it was the first (and most prominent) niche they were exposed to at the beginning. After a while, it becomes hard to make a change for some folks. I applaud you for your courage and foresight in following your passions and profits that exist in those niches.
Based on your approach to the big change, I'm sure you will find yourself having more time to do the things you want to do at the same time you'll most likely see more progress everyday because as as you observer you won't be juggling too many balls.
Best Wishes.
