My father taught me that you can you read a hundred books on wisdom and write a hundred books on wisdom, but unless you apply what you learned then its only words on a page. Life is not lived with intentions, but action.
You are an explorer, and you represent our species, and the greatest good you can do is to bring back a new idea, because our world is endangered by the absence of good ideas. Our world is in crisis because of the absence of consciousness.
There will come a time in your life when you lose something that matters to you. You'll fight for it and you won't win. But what really matters isn't the war you're waging, it's that you don't lose the person you are in the midst of the battle.
Okay, this is the wisdom. First, time spent on reconnaissanse is never wasted. Second, almost anything can be improved with the addition of bacon. And finally, there is no problem on Earth that can't be ameliorated by a hot bath and a cup of tea.
All truly wise thoughts have been thought already thousands of times; but to make them truly ours, we must think them over again honestly, until they take root in our personal experience.
