Here's a quote by W. Clement Stone.
"Thinking will not overcome fear, but action will."
Does thinking change situations? We all know the answer clearly. Thinking without action is similar to empty talks (talk big with no actions).
We have to start doing something, use actions to make things happen. Fears can be overcome with strong determination and willpower.
We have to face it, accept it, and conquer it.
So, start taking the right action today.
"Most of us will fail someday.
Most of us will have regrets.
Most of us will experience grief of loss.
But no matter what we faced, life still goes on.
Life itself is a learning process."
