Making right choices in the things pertaining to God will have positive repercussions in every aspect of your life. Whether you make a sports team or not is a trivial matter. However, a strong relationship with God will help you to deal with success in this matter or failure. Making Godly decisions in your life is not a "good luck charm" guaranteeing success. However such decisions consistently applied will, in the end, lead to eternal life. That's a prize well worth striving for!
