For me it is required to be a master of both things like of course you can not have experience if you are not going to try and some people would think it's a waste of their time if they are doing what they know already like repeating their work over and over again. So it should be in a balance.
I would also agree that its a combination of both being smart and strategic because the determination of being smart to be is a function of being strategic on some specific things among the importance which include financial freedom and source of this is different and several people manage it differently the moment they are able to keep it together, then they are good at it.
