Generally, I’m not a big fan of dissecting what “successful people” do.
The promise implicit in “doing what they do” is that you’ll become successful too.
I think the road to success, however you choose to define it, is more complicated than that. A path taken by one person may not be the right path for you.
So let me qualify my headline by saying, “When I find myself dabbling, it’s a sure sign I’ve wandered off my own path to success.”
In other words, this is what’s true for me. It may or may not be true for you. (But I suspect it might be.)
