Look back to the old days: people bought an MS DOS machine and struggled with it for weeks to bring it up to speed. Then Apple created Macintosh, struggled a bit with it, but eventually succeeded. Then it went into other businesses. If your company truly wants to change the world, it would make these problems go away for customers.

The most powerful sign is that your work no longer enchants you - it's not deep, delightful, and mutually satisfying. When this happens, it may be time to look for new challenges.

Accept diversity and don't take any crap.

Just be nice, take genuine interest in the people you meet, and keep in touch with people you like. This will create a group of people who are invested in helping you because they know you and appreciate you.

The hard part is implementing the decision, not making it.

Remember that nobodies are the new somebodies.

My recommendation for SEO is very simple. It’s Write Good Stuff. In my mind, Google is in the business of finding good stuff. It has thousands of the smartest people in the world, spending billions of dollars to find the good stuff. All you have to do is write the good stuff; you don't need to trick it. Let Google do its job and you do your job.
