Differences.

A professor shows the audience an empty jar.
He fills the jar with rocks until no more can be added.

Professor: Is the jar full?
Audience: Yes!

He grabs a handful of smaller-sized rocks and put them in the jar

Audience: Aww he got us!
Professor: .. Is the jar full now?
Audience: Yes!

He grabs a handful of sand and pours them in

Professor: Is the jar full now?
Audience: No? ..Yes?

The professor gets a cup of coffee and pours it all in the jar.

Professor: ...now it's full.

What does this tell you?

Life is compiled with many small things in life. Just make sure you take care of the big pieces first. And as for the coffee, it doesn't hurt to have a cup once in a while with your friends.

Coach Barr and I talked about my dismissal in basketball and asked if I had spoken with Yenchik. I told him that I haven't, so he told me about this little experiment with the professor. He kept me thinking all day (even now), in a good way of course, so I thank him for that. He made me realize that I should not worry about the little things around me, but the things that I am more committed to, things that will affect my future, things that will create the person who I will become, things that I will be proud for, and never giving up.. I'm sorry for all those I have let down. This was a silly mistake I should have not made in the first place. My fellow Sixer ballers, I am proud of you guys. These are words from my heart and I wish you guys the best of luck this year. Apparently, there will be no more athletic sports next year so I won't be able to enjoy the final season with you guys. To Yenchik, you are a hot-headed coach and I think you can be an asshole at times, but I thank you as well. You've created a man out of me and throughout all of this, honestly speaking, you were like a second father to me. You have taught me so much and I have used your words and applied it to my life. I'm sorry to let you down the way I have and I seriously regret it. But like they say, life goes on...

Lol, sounds like a fucking suicide letter, but at least I have let it all out.
