There are always more tomorrows than yesterday’s for the universe. For us mortals we have an expiration date. So our yesterdays at the mid point will begin to outnumber our tomorrows.
I’ve seen people try to make tomorrows yesterday more memorable than yesterday’s tomorrow. Little clue for you, both are today.
We can learn from our history to influence our path for the future, but we will never reach it unless we take steps in the present.
