I'm not one to swear, but I do get very frustrated when I'm doing something and it goes wrong or things don't respond as they should. I think it's good advice to stop, rest your mind, and then continue. Sometimes the very fact of being overwhelmed, tired or disappointed can cloud our minds and we don't see the solutions. As for Tesla, what can I say! Better watch the bulls from the sidelines. I send you a hug, my friend :)
