The first quote is "Sometimes, in life, you are the windshield, and sometimes you are the bug." (source unknown).
Then he shares a longer quote:
Be of good cheer.
Do not think of today's failures,
but of the success that may come tomorrow.
You have set yourselves a difficult task,
but you will succeed if you persevere;
and you will find joy in overcoming obstacles.
Remember, no effort that we make
to attain something beautifulis ever lost.
Finally, Paul shares: "If you have smashed into something recently, or if something has smashed into you, just know that you are not alone! Everyone experiences WINDSHIELDS and BUGS occasionally, and right this moment there is someone out there who has survived the yuckiness you're facing, and there is almost certainly someone waiting to help you whether you need a pat on the back, some advice, or perhaps a few squirts of Windex! Peace, Paul"
It's always nice to be reminded that we aren't alone, no matter what we're going through.
