Whether it's something personally or professionally, one obvious (but many times overlooked) key to making significant improvements is this:

If you want to get better than you are, you have to get yourself around someone better than you are.

Someone more experienced. More skilled. More savvy. More talented. More proficient. More gifted. More excellent. Someone better than you.

Humble yourself. Find a way to work your way into their life. Get close enough to observe. Get close enough to ask questions. Get close enough to be able to take notes.

Notice the nuance. Watch the way. View the variance.

Though this will take intention, it will be worth it.

But, just in case you're not willing to put in the work and effort to position yourself around someone better than you, here is a picture of the alternative.

You will hit a ceiling created by your own unawareness of how it can be done better.
Then, you will get stuck doing it "the way you've always done it."
Unfortunately, the people who need you to be better will miss out.
Finally, your full potential will go unrealized.

I don't want this to be me. I don't want this to be you.

Get around someone better, and get better.
