Sincerity - one does not cultivate sincerity, for to do so is to render it insincere. So in other words, sincerity is a quality that requires brutal honesty with oneself; you must understand and be honest about your feelings, passions, values, thoughts, and when your actions are consistent with those, you have sincerity.
Dedication - it comes from a true desire for something, usually preceded by a passion or great interest in something. Few of us are truly dedicated to something that holds no value, passion or interest for us. All people are truly dedicated to some things, although they may not name them consciously. It seems you are indeed dedicated to self examination and improvement, and so you already have dedication in this area. Dedication is another quality that cannot be faked. Dedication is an authentic commitment (whatever the reason for commitment).
Commitment - similar to dedication, and this is what underlies dedication. People are committed to people, causes, things when there is personal value seen in doing so. Commitment may be dedicated to something because of the principle involved, and because the value system of the person committing understands it/holds it to be important in their personal estimation.
Another thought-- I am sure you love and respect your father's experience and views. But do not make the mistake of believing someone (even your father) knows you better than you know yourself. His statements may be based in personal interpretation and perceptions. For example, by virtue of having even asked this question, it seems you either already have, or certainly have the potential, for all 3 qualities. I wish you the best, I hope you hold a positive thought for your continued growth, and send you all encouragement in the journey.
