Nothing will ever happen in the future, it will happen in the Now.
What you think of as the past is a memory trace, stored in the mind, of a former Now. When you remember the past, you reactivate a memory trace - and you do so now. The future is an imagined Now, a projection of the mind. When the future comes, it comes as the Now. When you think about the future, you do it now. Past and future obviously have no reality of their own.
Any lesson from the past becomes relevant and is applied now. Any planning as well as working toward acheieving a particular goal is done now.
- The Power of Now by Eckhart Tolle
Be present. In the moment. In the NOW.
Because that's all we really have.
