You are right that none of us live close to that list, but that passage is not saying that if we dont we do not go to Heaven. The whole letter to Galatians was written because some people were trying to get the gentile and jewish believers to return back to the law. Paul was pointing out that the law has never and can never save us because of our corrupt sinful nature. However, being filled with the Holy Spirit produces a change in us. We are being changed from one degree of glory to another and He who began a good work in us will bring it to completion throughout our lives as long as we do not try to save ourselves by works but allow the Holy Spirit to have His way in us.
Paul is pointing out that if we try to enter the kingdom of God by our own works we will fail. But he also stated that "thanks be to God, through Jesus Christ that he has been set free from the law of sin and death" and we are now free to walk in newness of life by the power of the Holy Spirit
