This is what many of us should focus on doing. Because the moment in what we are living is what will prepare us for what will come later. The need to focus on the moment is what will allow us to get closer to where we want to be.
I am guilty of focus on the future more than the present. Then that had an effect on my present being. But you know what this is a societal trait that was picked up many years ago. Also I believe you possibly suffer from this as well.
So from now on focus on the present and what it is that you are doing. If you know that what you are doing is not beneficial to helping you get to where you want to be stop doing it. Stop wasting the valuable time that you have.
Listen to your heart and do what feels right to you. Many people can give you advice on various topics but you know what is right for you. The people may get upset with you about not doing what they recommended but thats ok. Remember you are living your life for you not someone else.
