Here is a quote my husband presented to me several years ago. It is a good boost. In realizing the author was a mountaineer I can see he knew the importance of being confident and going forward with conviction.
“Until one is committed, there is hesitancy, the chance to draw back, always ineffectiveness, concerning all acts of initiative (and creation). There is an elementary truth the ignorance of which kills countless ideas and splendid plans: that the moment one definitely commits oneself, then providence moves too. All sorts of things occur to help one that would never otherwise have occurred. A whole stream of events issues from the decision, raising in one’s favor all manner of unforeseen incidents and meetings and material assistance which no man could have dreamed would have come his way. Whatever you can do or dream you can, begin it. Boldness has genius, power, and magic in it. Begin it now.”
-William Hutchinson Murray, Scottish mountaineer, 1913-1996
