Seriously, what is it you like to do best? Even if it is only one talent, start putting it to good use today—right now. And then get the training you need to sharpen that talent and ask God how you can use it to serve him and help others so you can make your life count for something worthwhile.
Don't wait for opportunities to fall into your lap—they may or may not come. Make your own opportunities. If you find a need, meet it. If you find a hurt, heal it.
With God's help you, too, can make your life count for something truly worthwhile for time and eternity.
