I like the path St. Therese of the Child Jesus, she made it simple and pure. Getting to Heaven shouldn't be complicated and it isn't if you foster a true devotion to Mary. Pray for this devotion, because Mary will make sure that you are brought to her Son, Jesus Christ.
This is the problem with other so-called Christians, they dis-honor His mother and will not give her the title she deserves, therefore they find themselves within a smorgasbord religion, picking and choosing what they want and leaving behind what they do not want.
Also learn to trust God, "Sacred Heart of Jesus I Trust in Thee", a little prayer that should be said when you are making decisions, or when something happens that you do not understand why it happened. God does not allow us any crosses that we can not endure. Yet, as He took up His Cross, so we too will have them. Expect them!
Keep the Faith!
