Question: “I want to convert my life and be a Buddhist but how?”
You don’t.
“Converting” to Buddhism doesn’t make you a Buddhist, just like going to church doesn’t make you a Christian. It’s the practice and the way you live your life and treat others that makes you a Buddhist.
When Christians, Jews or Catholics come to Buddhist practice, they don’t practice to become Buddhists; they practice to become better practitioners of their own religion. Nothing about Buddhism is religious. Buddhism is mind-centered, not god-centered, so you can be anything and use Buddhist practices to make you a better person and live a better life.
Smile and be well!
