Energy

We only have a limited amount of it to use each day.
I'm talking about Physical, and Mental energy.
Both are connected.
Did you know that draining one can drain the other and vice versa?
Did you know that boosting one can fuel the other as well?
True stuff - at least in my life.

Negativity can tear you down emotionally faster than working 12 hours.
one negative encounter can sap your strength physically.
And what happens when that energy is gone?
The rest of your day is spent recuperating or trying to finish the other zillion things that need doing.

Positiveness ( if that is a word) does the exact opposite.
You could be dead tired but positive encouragement can help you dig into the physical reserves and push yourself even farther.
More on this subject later.
