“Be careful with your thoughts, for your thoughts inspire your words.

Be careful with your words, for your words precede your actions.

Be careful with your actions, for your actions become your habits.

Be careful with your habits, for your habits build your character.

Be careful with your character, for your character decides your destiny.”

– Chinese proverb

From a friend: This is a quote from Mahatma Gandhi, adapted with the prefixed “Be careful…” wording. I think it would be appropriate to attribute you quote to “Adapted from a quote by Mahatma Gandhi”.
