Chief is a long time fan of the Dallas Cowboys. That's the team he loved as a kid... and the team he still roots for today. He is critical of some of their players, staff and play calling, but he's stuck with his team through thick and thin. Despite their ups and downs... Chief has remained true. This speaks to his overall character.
Fair weather fans and band wagon jumpers are not the kind of people you want to keep close to you. You'll want to surround yourself with those who will stand by your side and weather the storm when things get tough. And more importantly, you should be that kind of person too. Life is tough enough, but being abandoned in a time of crisis isn't good for anyone. Just imagine how many marriages have ended because of this attitude. We need to endure the bad and celebrate the good... and it's much easier and a lot more fun when we do it together.
Life is ever-changing. What's good today, may be bad tomorrow and the opposite is true as well. Hang in there. Stick it out. If something is worth your affection now, it deserves that same loyal, affection down the line when the going gets tough.
And it will get tough.
