If you are a Christian, God has a specific and definite plan for your life. He works in a way that is different from what you may have been taught about the way He does things, and you must choose to carry out His plans rather than pursue your own. The choice is always up to you; He won't force you to obey Him. Be very choosy about the people with whom you become close friends; they can influence you for either good or bad.
The more you get to know God, the more you will see that He always has your best interest at heart in whatever He tells you to do. It may not be the plan you had in mind, but if you follow Him, you will look back and see how much better His path has been for your life than the path you might have chosen without His guidance.
