When things aren’t going quite the way you’d like them to, it’s often because you’ve lost focus on what really matters. But focusing on life’s fundamental truths can be difficult, especially when they remind you that you’re heading in the wrong direction.

The best things in life don’t come easily, and failing to observe yourself carefully is a sure path to mediocrity. I believe that Socrates said it best:

“The unexamined life isn’t worth living.”

Socrates’ observation also applies to business. When Eric Schmidt was CEO of Google, he famously said, “We run this company on questions, not answers.”

Life and business run on questions, not answers. You should be asking yourself regularly if you’re headed in the right direction.

Many of life’s essential truths need repeating. We need reminders that help us to stay focused on them. Keep these truths handy and they’re sure to give you a much-needed boost.

The biggest breakthroughs typically come when you’re feeling the most frustrated and the most stuck. It’s this frustration that forces you to think differently, to look outside the box and see the solution that you’ve been missing.

Success takes patience and the ability to maintain a good attitude even while suffering for what you believe in.

Success doesn’t come from movement and activity. It comes from focus — from ensuring that your time is used efficiently and productively.

You get the same number of hours in the day as everyone else. Use yours wisely. After all, you’re the product of your output, not your effort. Make certain your efforts are dedicated to tasks that get results.

Anyone who makes you feel worthless, anxious or uninspired is wasting your time and, quite possibly, making you more like them. Life is too short to associate with people like this. Cut them loose.

The circumstances you’re living in today are your own — you created them. Likewise, your future is entirely up to you. If you’re feeling stuck, it’s probably because you’re afraid to take the risks necessary to achieve your goals and live your dreams.

When it’s time to take action, remember that it’s always better to be at the bottom of the ladder you want to climb than at the top of one you don’t.

I often hear people say, “What’s the worst thing that can happen to you? Will it kill you?” Yet, death isn’t the worst thing that can happen to you.

The worst thing that can happen to you is allowing yourself to die inside while you’re still alive.

Life goes a lot smoother once you let go of grudges and forgive even those who never said they were sorry. Grudges let negative events from your past ruin today’s happiness. Hate and anger are emotional parasites that destroy your joy in life.

The negative emotions that come with holding on to a grudge create a stress response in your body, and holding on to stress can have devastating health consequences. Researchers at Emory University have shown that holding on to stress contributes to high blood pressure and heart disease.

When you forgive someone, it doesn’t condone their actions; it simply frees you from being their eternal victim.

No amount of guilt can change the past, and no amount of anxiety can change the future. It’s impossible to be happy if you’re constantly somewhere else, unable to fully embrace the reality (good or bad) of this very moment.

To help yourself live in the moment, you must do two things:

1. Accept your past. If you don’t make peace with your past, it will never leave you and, in doing so, it will create your future.
2. Accept the uncertainty of the future. Worry has no place in the here and now. As Mark Twain once said, “Worrying is like paying a debt you don’t owe.”

While it’s impossible to turn off your reactions to what others think of you, you don’t have to compare yourself to others and you can always take people’s opinions with a grain of salt. That way, no matter what other people are thinking or doing, your self-worth comes from within. Regardless of what people think of you at any particular moment, one thing is certain — you’re never as good or bad as they say you are.

Loss is a raw, visceral reminder of the frailty of life. It shouldn’t be.

Remind yourself every morning when you wake up that each day is a gift and you’re bound to make the most of the blessing you’ve been given. The moment you start acting like life is a blessing is the moment it will start acting like one.

After all, a great day begins with a great mindset.

Only when you embrace change can you find the good in it. You need to have an open mind and open arms if you’re going to recognize and capitalize on, the opportunities that change creates.

You’re bound to fail when you keep doing the same things you always have in the hope that ignoring change will make it go away.

After all, the definition of insanity is doing the same thing over and over again and expecting a different result.

Life doesn’t stop for anyone. When things are going well, appreciate them and enjoy them, as they are bound to change. If you are always searching for something more, something better, that you think is going to make you happy, you’ll never be present enough to enjoy the great moments before they’re gone.

Staying focused and asking the hard questions can be extremely uncomfortable. But we don’t learn and grow by sticking with what’s comfortable.
