How to deal with things distracting you from God?

Was a stronger christian when i was younger, and later years faith became stagnant because the fact I was a contrarian (went to christian school) I've started reading Pursuit of God and have been very moved by it. I'm starting to understand the insignificance of everything I'm chasing compared to following Him. How have you guys dealt with leaving things that are between you and God? Also, I enjoy science and was wondering if anyone has had their faith waver because of the 6 day creation?
