The best way for conversion (or reversion if you left the Church and are coming back) is to humbly petition the Lord by prayer to guide you. The Holy Spirit does wonders if you ask him.
In this excerpt from the Responsorial Psalm from today’s Mass of the First Sunday of Lent…
Psalm 25: 4-5
“Lord, demonstrate your ways to me, and teach me your paths.
Direct me in your truth, and teach me. For you are God, my Saviour…”
via Catholic Public Domain Version of the Sacred Bible
…we see the psalmist do just that while also recognizing the authority and legitimacy of God to do this (“”For you are God, my Saviour”).
The psalm for today’s Mass is a wonderful prayer of petition.
