Bhim wasn't able to trust himself or feel as confident with his choices because it was such a strong part of his culture to meet expectations of others (and especially parents) and NEVER embarrass your parents with your choices. Maybe it was Rebecca's choice of career, in part, that hurt her self esteem. How many times can you be told over and over "no, you are not right for this part", "no, we are looking for someone thinner (or funnier, or better looking, or ________________). And then after hearing it all day at auditions, your parents reinforce it whenever you talk to them. I think a lot of her acting out was in some way to punish herself for disappointing her parents. She felt guilty but wanted to stay true to herself. She just wasn't sure how to manage the two things together.
Speaking for myself, there were times I dismissed my son's ideas or plans and attempted to "lead" him in another direction. My thinking at the time was that I desperately wanted him to have less hurt, less failure, and more opportunity that I did. I tried to shield him from life's disappointments and challenges. I assumed that I knew better for him because I had more experience. So I definitely understand what Pival means when she says "happy in the right way".
