Manufactured fear

Can we enjoy the food on our lunch table, without worrying about our dinner?
Do we usually worry about our next breath while exhaling?

The answer to both of these questions lie in the fact that we project ourselves so far into the future, that we forget that the only moment we actually possess is "now". 

We don't worry about our next breath, because our body understands this simple concept that our "modern" mind has forgotten.

Animals, guided by innate reflexes and habits, don't spend their day worrying about their next meal. They lounge in the sun and when they feel hungry, they go hunt or graze.
A dear feels fear at the sight of an alligator, but once it manages to escape, the fear vanishes and the dear resumes its tranquil life.
We, humans, can't relax and enjoy our lives unless the past has been dealt with and the future is secure and safe.
We might ask ourselves, is our thinking really helping us?
Thinking is useful for practical matters, like calculating the amount of money we need for our purchases for example, beyond similar tasks, our thinking has made us miserable beyond comprehension.

Thinking becomes problematic when it is involuntary. 
The widespread consumption of alcohol, and other recreational drugs is a testimony to how hard we try numb our brain and keep it from senseless thinking.
Once our brain is on “mute”, we feel freer, we are more relaxed and eager to explore life.
We are an entity divided amongst itself, in an eternal internal conflict, constantly oscillating between our "unconscious" state and our clinging of our conscious thoughts that wants to grab, understand and dissect.
