There is only one difference between an old man and a young one: the young man has a glorious future before him and the old one has a splendid future behind him: and maybe that is where the rub is.
When I was a teenager, I felt that I was just young and uncertain—that I was a new boy in a huge school, and I would have been very pleased to be regarded as something (which was) so interesting as a problem. For one thing, being a problem gives you a certain identity, and that is one of the things the young are busily engaged in seeking.
I have three questions. May I have your pionts? Thanks.
1. What the meaning of the red 'something' here?
2. Can I reword the blue sentence as the following without changing the meaning?
I would have been very pleased, if anyone had regarded me as something so interesting as a problem.
3. Is the words 'which was' in brackets omitted?
