A book I have has a lot of quotes, my favorite one is “Real difficulties can be overcome; it is the imaginary ones that are unconquerable.” Theodore N. Vail said that.
When one was young, he had many irrational worries. Then comes a book. Has many stories. With every story, a quote or two. Reading one or another makes a difference. One quote really sticks out to this young man. Sheds some light this quote has done. Relax the worries this quote has done. A different person he has become.
