I think I would have liked to be as confident about myself as I am now. I would have liked to change a little about my personality, by which I mean I would have liked to be more selfish and less generous with people <em>(note: are you sure you haven't mixed up 'less' and 'more'? most people would rather be less selfish and more generous)</em>, and I would have avoided my relationship with my second boyfriend. Nowadays I have to pay off two mortgages because of him, but fortunately I can afford them.
Also, I would have liked to study interpretation and translation, but I suppose is too late <em>(note: it's never too late!)</em>. Otherwise, I think my life is going pretty well. I have my health, a good job, and very good friends. What more could I ask for?

You did an excellent job with your English in this notebook entry!
