There's one thing I've learned that you can learn and apply every day. It's simply, Learn 1 NEW thing every day!
I've used this simple philosophy in every area that I care about. Now, no one is an expert on everything and very few can be called "experts" in anything.
Here's what you do. Pick a subject you'd like to learn more about, for instance "online marketing". Learn one NEW thing about online marketing every day. At the end of a month, you'll know at least 30 new things about online marketing you didn't know before!
Don't think you'll be able to remember everything you've learned? Simple! Start a journal and label it with the subject you've chosen. I put mine right in my dock. Add an entry every day and go over it weekly. Pretty soon, these entries will be ingrained in your mind and you'll remember every one. The next time you come to something new, add it to the journal, or check to make sure you've not already entered it.
Pretty soon you may not be an expert in that area, but you'll know a heck of a lot more about it than you did before.
