SEO question about titles of posts?

[Peter]

Life Quote 1 and so on is terrible idea.

You can do it this way:
Url should be http://www.quotes.com/Albert-Einstein
Title should be Albert Einstein Quotes
on page you should have one H1 tag with content Albert Einstein
and all his quotes should be as H2 - "E=mc²" and bellow with explanation when and where this is said, link to external sites and links to other categories/tags.

This is almost perfect on-page SEO optimized page. If you're doubt check WikiQuote about their approach - it's same.
