I think you can start by giving up drinking and smoking first. I’m not saying it’s wrong to cop a buzz once in a while but if it becomes a regular thing then you might be walking on thin ice. As children of God we’re told bear good fruit by abiding in Christ. Therefore, it’s important to distinguish what’s bearing fruit in your life and what isn’t. Likely, listening to angry “Christian” music may not be very Christian like at all. In fact, some of these things which you enjoy might actually be hindering your walk with Christ rather than bringing you closer. We’re constantly being influenced by the things that we’re inputing into our minds, that’s why it’s important to be cautious about what surrounds us. Following Christ means being able to deny ourselves of the things that we desire and put Christ first above all. If you’re able to do that, you’ll bring yourself even closer to God and become a more effective youth pastor by allowing him to work through you.
