Focussing on the present sounds like a spiritual good thing. And maybe if you can't get over something that happened in the past and you're becoming obsessed by it, it might not be a bad idea. Or if you're obsessively worrying about the future, a bit of here and now might be restorative.
But it's a bit Truthy, focussing on the present, being here now.
Too much focussing on the present curtails any analysis of the past, which is essential to make a judgement.
I'm currently writing some code for an irrigation app. I've got to make two calls to a weather API - one to get the current conditions, and another to get the historical conditions. Just the current conditions isn't much use in deciding whether the irrigation should switch on. In fact, if I could only make one of the calls, the historical data would be more valuable.
It's like the stage magician, making you look here now, when if you want to see how the trick is done, you really need to look anywhere but where he suggests and try to keep a track of what has gone on.
