It’s obvious you can’t plan for the past, because it’s gone, and it’s just as obvious you can no longer plan for the present because it’s gone too. As soon as you think about “now” it’s gone. You can choose to be mindful of the present but even when you succeed with that awareness of what feels like the present moment it’s already past.
Perhaps what you can do is to generate habits that will spontaneously pop into action without your being conscious of the pre-planning at the moment of action. Most of your actions are like playing ping-pong; you keep your eye on the object of interest and let your body twitch a multitude of muscles to do what you want to do externally. You don’t think about philosophy or some wonderful words of wisdom, you hit the ball in the direction you want it to go in the future moment after it leaves your paddle.
A lot of life is like that, but there is a part of thinking that we like to believe is free will, that we are making decisions. It is in those moments that we are paying attention to what we are going to do. What we are going to do in this moment of thoughtful action and what we are going to do in this instant that will become part of history, an act that is forever fixed history. This decision is thought of as a mental act, and yet it may be a lot more like those moments of playing ping-pong when you just do what seems right and hit the ball so it goes where you want it to go. There’s nothing fancy about it. But one thing that you can do in those moments of decision is to be pointed toward a worthwhile goal.
We bring our whole being into the process of conscious decision-making and ultimately it’s so complex it’s like hitting a ping-pong ball in the right direction.
