Found on goodreads.com after a rather frustrating day:

“And I got out of there without punching anyone, kicking anyone, or breaking down in tears. Some days the small victories are all you achieve.”
― Molly Ringle, Relatively Honest


“It's not like I'm all into nostalgia and history, it's just that I can't stand the way things are now”
― Novala Takemoto, Missin' (Novel)   

“In my small way, I preserved and catalogued, and dipped into the vast ocean of learning that awaited, knowing all the time that the life of one man was insufficient for even the smallest part of the wonders that lay within. It is cruel that we are granted the desire to know, but denied the time to do so properly. We all die frustrated; it is the greatest lesson we have to learn.”
― Iain Pears, An Instance of the Fingerpost  

“[Y]ou are here to learn something. Don’t try to figure out what it is. This can be frustrating and unproductive.”
― Steven L. Peck, A Short Stay in Hell

How is it that our memory is good enough to retain the least triviality that happens to us, and yet not good enough to recollect how often we have told it to the same person?  ~François Duc de La Rochefoucauld
