Let me challenge you to go read this blog by John Piper: http://blog.worship.com/worship/2007/01/how_to_deal_wit.html
This is just one quote to get you interested:
The Main Tragedy
The great tragedy is not mainly masturbation or fornication or acting like a peeping Tom (or curious Cathy) on the internet. The tragedy is that Satan uses the guilt of these failures to strip you of every radical dream you ever had, or might have, and in its place give you a happy, safe, secure, American life of superficial pleasures until you die in your lakeside rocking chair, wrinkled and useless, leaving a big fat inheritance to your middle-aged children to confirm them in their worldliness. Thatâ€™s the main tragedy.
The Point: Your Life
Whatâ€™s the point of all that? The point is not this is what you do with your loose change. The point is: This is what you do with your life. You donâ€™t want always be sitting high in your SUV dropping nickels into other peopleâ€™s dreams. Satan wants that for you. But you donâ€™t! You want to dream your own dream for the glory of Christ. Why am I on this planet? What has God put me here for?
