A life changer for me was the day I learned: ACTIONS SPEAK LOUDER THAN WORDS!. People can say all sorts of things and fool not only themselves but you in the process but actions are real! So in the context of mixed signals - I agree 'Indecision IS a decision'.
'Awareness' is the first and sometime the most difficult step in personal growth and / or change. Simply being aware to look out for what a person does rather than says is a positive move in the right direction. Observe people - Actions tend to speak the truth and most certainly much louder than words.
