First, it’s not possible, living in the future I mean. Thinking about the future is great if you are in planning mode. Hiding there to avoid an unpleasant present is not a good use of the present or your planning time. You actually plan in the present based on your glimpse of a likely or desired future. Take care to think about how you want to be in the future but take action in the present to make it happen.
Thinking about the future without planning and action changes nothing. Too much time in the future can lead to anxiety, worry and stress. You can worry about things that haven’t happened yet or will never happen.
The present is all you have. Make the most of it. Careful you don’t miss it.
