Thankfully, this may be enough: these quotes, words of wisdom, proverbs standing the test of time and always improving your productivity. To go one step farther, though, we'll break them down for you, making it clear. Because that's all we really need, right? Clarity. Like crystal.
"Men's Best Successes Come After Their Disappointments." -- Henry Ward Beecher
Simply put, don't be afraid to fail. Be motivated to screw up. Thank the lucky stars for being a failure. That gives you the opportunity for redemption, and there's nothing sweeter.
"Do Not Wait to Strike Till the Iron Is Hot; But Make It Hot by Striking." -- William B. Sprague
Be active. Tenacious. Tough. Ambitious. Set the trends. Take a risk. Think beyond the box (or better yet, just toss the box completely!).
"Motivation Is a Fire From Within. If Someone Else Tries to Light That Fire Under You, Chances Are It Will Burn Very Briefly." -- Stephen R. Covey
No one can motivate you but you. You are your greatest cheerleader. You're also your greatest critic. You pick which one you'd rather be!
"Success Is Not the Key to Happiness. Happiness Is the Key to Success. If You Love What You Are Doing, You Will be Successful." -- Albert Schweitzer
Please don't ever choose a job based on the prospects of high salaries, bonuses or industry trends. The bottom line is if you'll hate the job, you most likely won't last long in it. Always find something you love to do, because you know you'll do it well. And ultimately you'll profit from it.
"Desire Is the Starting Point of All Achievement, Not a Hope, Not a Wish, But a Keen Pulsating Desire Which Transcends Everything." -- Napoleon Hill
Hoping to be a Nobel Peace Prize-winning scientist won't get you anywhere. That's putting too much faith in the world, gambling by chance and daydreaming. It's all well and good, but if you don't have the desire to pursue that dream, you just won't get anywhere!
"You Can Have Anything You Want If You Are Willing to Give Up the Belief That You Can't Have It." -- Robert Anthony
"I can't" never could, basically. Your ability to direct your path via your own voice is absolute. If you say you can't have it, you won't. No matter how much you want it.
"Great Spirits Have Always Encountered Violent Opposition From Mediocre Minds." -- Albert Einstein
Lastly, the great scientist said it best: people will disagree with you, especially if you have an ambitious thought, or idea, or prospect. Don't be discouraged. Expect it. Face it. Embrace it. And prove them wrong.
