You'll see a lot of people saying you should just jump in to avoid "Analysis paralysis".But I think this should be framed or caveated with the importance of education, which a lot of folks on the forum do.In my opinion, you’re approach is excellent.You’ve created a game plan (thru your business plan) and outlined a timeline.Now you have specific criteria which will prevent sensory overload and limit the effects of the “next shiny object”.In addition, your timeline should ensure that you don’t sit on the sideline indefinitely.You’re well on your way!

At one time, these were effective but why are they not as effective as in the pass.
