Imagine you were diagnosed with an incurable disease today, you'd start to think a whole lot different about life.
Imagine you lost your leg today in an accident, you couldn't walk, sprint and lift anymore. You would hate yourself for complaining about "not feeling like exercising"
Imagine you found out you had fatal insomnia, you wished you would have appreciated your good night sleeps you had before.

I'm just saying, sometimes I can't stand hearing people being totally upset and complaining about the weather, or their clothes being dirty, that type of stuff.
Just be thankful for all the health that's given to you. That's what I try to do. When I wake up after a good sleep, and start my delicious breakfast, and feel good physically, I realize how awesome life is and there's nothing that can kill my mood and I wish that feeling would stay forever.*
This was extremely corny, but I think it's true, and I think there are way too many people not knowing what they got.*

Just something to cheer you up
