Curveballs

Ever been thrown a curveball by God? I tend to get them a lot. Most of my life I am being thrown a curveball or 2 all a time. When that curveball is thrown, do you catch it? Or does it hit you hard? I've been thrown 2 curveballs in the last little while, and both of them I have caught but they have slipped out of my hands and fallen on my foot. I've been going through a time in life where I wonder what my purpose on earth is. Which in my mind, is not a good thing to wonder, because it meens that you are not happy with your life. I'm working through a few things right now that are affecting my attitude a bit, and are making me wonder why I am here. I feel that when God is telling me something, I need to go out and do it. but when things get in my way, I get frustrated and dont know if I should give up or not. If God keeps on throwing those curveballs to me, sooner or later I'm going to have to catch one. I'm really hoping that that day comes soon.
