“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 issue 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 come his way.” _William H. Murray
Sometimes you just have to start.
If you wait until you know for certain that you should act, or until you are absolutely confident of the outcome or until you have a solid plan with a predetermined time table and have all the resources upfront that you will need…
…you will most likely never achieve anything significant.
Most often you just have to jump into the deep end of the pool and start flailing away like your life depends on it.
