70.) The best investment you'll ever make is in your own education.

It doesn't even have to be a financial investment.  Set aside a few minutes a day read a book on a topic that interests you.  Join a self-guided study site.  You'll never regret knowing more than you need to, especially on a topic related to your profession.

Rant

There's not a year that goes by where I don't thank God for my college education.  Without all that practice knocking out term papers the morning they were due, I'm not sure how I'd ever get my taxes done.

56.) Technologies improves so fast that, that before you can master any new hardware, software, or system, it will be supplanted by the next generation of technology. 

Rather than becoming an expert on any one technology, focus your efforts on training yourself to unlearn and re-learn new technologies.

Some Rules Kids won't Learn in School

Some rules kids won't learn in school

Unfortunately, there are some things that children should be learning in school, but don't. Not all of them have to do with academics. As a modest back-to-school offering, here are some basic rules that may not have found their way into the standard curriculum.

Rule No. 1: Life is not fair. Get used to it. The average teen-ager uses the phrase, "It's not fair" 8.6 times a day. You got it from your parents, who said it so often you decided they must be the most idealistic generation ever. When they started hearing it from their own kids, they realized Rule No. 1.

Rule No. 2: The real world won't care as much about your self-esteem as much as your school does. It'll expect you to accomplish something before you feel good about yourself. This may come as a shock. Usually, when inflated self-esteem meets reality, kids complain it's not fair. (See Rule No. 1)

41.) Freely teach other people what you know. 

People, most especially coworkers, resent those who are stingy with what their knowledge, but they respect teachers, even after they've surpassed them.  This goes double for people in the technology sector.

38.) If you cheat in engineering classes, you will kill people later.

For your own sake and everyone else, either quit or learn the material.

28.) Read the great speeches.

While books reveal the knowledge of an era, it's the great orators who reveal its spirit.

Steve Jobs: Advice to New Graduates

"Again, you can't connect the dots looking forward. You can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future. You have to trust in something: your gut, destiny, life, karma, whatever. Because believing that the dots will connect down the road will give you the confidence to follow your heart even when it leads you off the well-worn path, and that will make all the difference."

"Remembering that I'll be dead soon is the most important tool I've ever encountered to help me make the big choices in life. Because almost everything - all external expectations, all pride, all fear of embarrassment or failure - these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to loose. You are already naked. There is no reason not to follow your heart."

"Have the heart to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary."

16.) Practice does make perfect - deliberate practice.

According to K. Anders Ericsson, the three components of deliberate practice are setting specific goals, receiving immediate feedback, and focusing on technique over results.

11.) You don't really understand something until you've taught it to someone else.

Whether it's self-defense or particle physics, if you really want to master a subject, go back and introduce someone with absolutely no experience whatsoever to the subject.

10.) Do yourself a favor. Learn to study as early in life as possible.

"Never memorize what you can look up in books."
- Albert Einstein

I can't pinpoint an exact source for this quote, but I love it. I can only imagine that, if he were alive today, Einstein might have said, "Never memorize what you can Google."
