What is it to you personally?
I've thought a lot about this, and I'm sure other people have too, but if you think deeply into this subject, I'm sure you'll find a lot of great things waiting for you. To me, life is a gift. It's a blessing. God gave you a life, and you have the possibility to change the world. You can change someones life just by smiling at them. You can save someones life just by telling them about that awesome dude chillin' up in the sky.
Every single person on this planet has the possibility to do great things. It's up to you to pursue your dreams, and fulfill your life. Not everybody pursues their dreams. If you think about it, all those great men and women in history all had a dream right? They PURSUED it. Life is a fantastic journey that lies ahead of you. There will be obstacles, and walls that you have to tackle down. Why? Why does God let difficult things stand in your way? Why is life so hard sometimes?
There might be challenges in life that break you down, but you'll get built back up. And when you do, you're a stronger person. And you will be prepared for the next difficulties in life.
