To make the right decision, we must ask the right question. For example, if we ask "What do I want?", we are setting ourselves up to make the wrong decision, for reality is not based on what we want but on what God wants.
To make the right decision, we must decide by faith and not by sight (2 Cor 5:7). For example, Lot saw that the land of Sodom and Gomorrah looked like the best land (Gn 13:10-11). So he chose to settle there. Little did he know that this land would soon be destroyed, as fire and brimstone rained on it.
To make the right decision, we must not automatically choose the easy way, for the easy way often "leads to damnation" (Mt 7:13), while the rough way of the cross leads to life eternal (see Mt 7:14).
To make the right decision, we in our culture of death must choose the road less traveled and sparsely traveled (Mt 7:13-14). In our culture, the popular position is usually wrong. The majority is more likely to be immoral than moral.
To make the right decision, we must first decide to give our lives to Christ. Decide for Christ now.
