Most of all, always keep the lines of communication open. Informally seek out advisors. Everyone wants and needs a mentor, but finding one is not so easy. Rather than seeking a formal mentoring relationship, look for informal advisors in people who you admire and respect. Always respect those who are ahead of you.
True leaders know when to lead and when to follow.
It certainly won't help you in your quest for a mentor. On the other hand, know when to stand your ground when you are being treated unfairly. Take assertiveness training if you feel that can help you. It is good to have an end to journey towards, but it is the journey that really matters most, in the end.
