Only purpose of human life is to serve and do penances for Supreme Personality of Godhead Krishna.Transform lust into service.There is no easier and better way to come to Goloka Vrindavan topmost planet in whole existence.Chant Hare Krishna maha mantra and be happy.Read Bhagvad Gita with Open mind and humble attitude all answers for all questions are in there.Try the process and you Will see iz Works if you are not od demonic nature and are sincere to reach God.Hare Krishna brothers
