God has given all of us special gifts in order for us to special things, but there are certain things that we cannot do, were not made to do, and in turn... shouldn't do! Again, this isn't bad, it's just something that we need to accept. Instead of telling ourselves we can do whatever we put our mind to, why don't we start putting our mind toward figuring out what we were designed to do. If we can determine our gifts and what we are good at, we can figure out our purpose and why God put us in this world. What is it that you enjoy doing? What is it that you can't help but love when your in the middle of? Whatever this is, it's more than likely what God wants you to be doing with your life. Max Lucado said it best in his book Cure For The Common Life, "You cannot be anything you want to be. But you can be everything God wants you to be."
God has given You, and only You, the set of gifts that you have. There is only one of every single one of us. Every person on this earth was made with a purpose, made to do something, made to glorify God in our own unique way and if you don't do what God intended you to do, the whole world will miss out. Not only that, but if your not living out God's purpose for your life, you will never feel truly happy. Not that life won't move on or be fulfilling in some way, but there will always be something missing and that feeling will never go away. We have one chance, one life, to be the person God wants and needs us to be. If we don't live out God's will, it will never be lived out. No one else can do what you were put in this world to do. No one else can affect the lives that you were put in this world to affect. You can't be someone that you aren't! You can and should be the uniquely wonderful person that God strategically designed you to be. God made every one of us different for a reason! Now it's time to figure out what that reason is and live it out the way God wants you to!
