They're all kids. And the sooner they realize that none of this sh#t matters, the better off they will be. For Christs sake, Sipple still hasn't figured it out so I understand when kids take these things too seriously. It doesn't matter.
If you have to look for outside sources to find positive fuel, motivation towards your goals, then you're missing something. It goes both ways. If you allow negativity from outside sources, especially people you don't even know, to truly affect your life, then you're missing something.
Be your own source of fuel. Find reasons in your own life to be up. Don't look for reasons to be down. I'm no expert but God as my witness, if you had a clue about all the things that could have me down right now, you would just trust me. There are days when I have to find things to be excited about. And I do.
