My will or God's will?

John 7:17 If anyone’s will is to do God’s will, he will know whether the teaching is from God or whether I am speaking on my own authority.

I had a great discussion with friends tonight about the future, marriage, children etc. All of us have spent time fantasizing about the future and what we'd like it to look like. Some of us have even come up with a timeline of when these events should take place. 

But have we ever stopped to ask "Is this what God wants?" 

I know we all are aware of our wants and desires. But if they do not glorify God then what is the use? Even if they will glorify God, how do we know if this is His plan?

As a college student I am constantly asked "What do you want to study?" "What do you want to do with your life?" "What will make you happy?"
It is not surprising in this individualistic and secular society that these questions revolve around what each individual wants. What about what God wants? Shouldn't this take precedence above our own desires?

Going into college I wanted to be an actress. I wanted attention and I wanted to be happy. A few years later, I am much wiser. I have been praying for discernment about what God wants for my life. He made it clear to me about 8 months ago that I am to devote my life to the pro-life movement. It is so incredibly amazing to know that I am starting to follow God's path for my life! 

As far as other things go, lately I've neglected to ask God what He wants me to do. I know in my heart that if one follows God's will rather than one's own, happiness at a greater level than one knows will result. 

I have really begun to open my heart to the Lord, surrendering my whole heart to Him. And I am experiencing a happiness I never had before.
