Watch your thoughts; they become words.
Watch your words; they become actions,
Watch your actions; they become habits.
Watch your habits; they become character.
Watch your character; it becomes your destiny.

I found this in Richard Rohr’s book ‘Breathing Under Water: spirituality and the twelve steps’

“The believers whose faith is most perfect are those who have the best character.”
Hadith of Abu Dawud and Sarimi (Found in p60 GBIB by J Mabey
