The limits lifted by our imagination are too great to explain in words. Imagination paints a future we can build and dreams to which we can aspire.
Imagination also can be a tool our brain uses to paralyze us and make us fearful.
Imagination is helpful and destructive depending on your spirit. But, in both ways imagination is a liar.
The dreams are rarely THAT good, and the suffering is seldom THAT bad.
We suffer more in our imagination than in reality. That should prompt us to dive more whole-heartedly into the good dreams and aspirations and leave the worry far behind.
