Okay, maybe it's not. That's not the point. The point is, life is what you make of it. Life is not so much about what happens to you, but more about how you react to it. What's your attitude towards life?
You don't need a reason, just wake up one day and have a positive attitude. You'll see how when you do this, it's harder for things to bring you down. Waiting in line is not so bad, missing your bus isn't the end of the world.
Think about how lucky you already are by just being here. Think about all the things you are able to do. If somethings doesn't work out, try something else. Life is full of possibilities and opportunities. Don't be afraid to risk now and then. Having a positive attitude affects not only yourself but also others in a good way. Spread the love.
Smile at the sight of a cloudy gray day. Say thank you to the grumpy bus driver. Give directions to a lost student. Help an old lady with her groceries. Make love life.
