The most important thing that I know is that knowledge pales in comparison to wisdom. Without wisdom, you won’t know how to apply knowledge. Get wisdom.
Let me elaborate a bit. Knowledge, facts, are like tools. Just having a tool isn’t enough, you need to know how to use the tool, and use it properly, to effect change.
Imagine you had a master car mechanic in your family, say your Uncle, that died and in their will they left their entire shop and all their tools to you. The day you found out about it, you and your friend go down to your new shop to investigate. Your friend is amazed at all the new tools you’ve accumulated, and asks if this means you can fix his car now. To this, you reply, “No, I don’t know anything about fixing cars, but thanks to my Uncle I have all the tools you’d ever need!”. Exciting maybe, but not helpful if what you really need is your car fixed.
We can find lots of knowledge nowadays thanks to the Internet, but without Wisdom you won’t know what to do with it all. Discover the wisdom you have within.
