My own personal motto is:
"If you don't like what people are telling you, get new people."
Okay, maybe it sounds a bit arrogant, but you probably would not even be reading this if you did not have more than a modicum of good sense. You can probably tell if an idea you have will fly, might fly, or will definitely not fly. Just because there are a lot of naysayers out there, it doesn't mean you should give up on an idea that you truly know is good. Sometimes you just need to surround yourself with the people that will encourage you to make it happen.
Okay, so what are a couple of other phrases that make me smile? I came across one by Andy Roddick of tennis fame that makes me say "how true." His quote is "at one point in your life you either have the thing you want or the reasons you don't." Sometimes you can't do what you want and instead of just making flimsy excuses, you realize that there is a trade-off to why you are not where you want to be at a given point in time. That is truly okay as long as you understand why, and don't just complain about not achieving that goal.
A third quote that is a bit fanciful is from Helen Keller. At 19 months, an illness left her deaf and blind and yet in the latter part of the 19th century, instead of being kept away from society, she learned sign language, was an author, was friends with Alexander Graham Bell, Charlie Chaplin and Mark Twain and travelled to over 40 countries. Her words to live by are "life is either a great adventure or nothing."
What are your words that will inspire me?
