Your mention of wishing you could rewind time reminded me of a new TV show – Ordinary Joe – about a guy who wonders what would have happened had he made a different choice at his graduation. The choice was a minor one, who to celebrate with, but it turns out one that creates three very different time lines. Actually Joe is the kind of Guy that panic’s when a choices is required and seems to prefer when others or situations makes the choice for him.  Of the three paths the show explores, all of them have their problems and missed opportunities.

Also reminded me of a Book THE MIDNIGHT LIBRARY by Matt Haig
Its about a woman who life has been full of misery and regret. She feels she has let everyone down, including herself and decides its time to end things. Between Life and Death she finds herself in the Midnight Library  where she gets to sample every timeline that every choice might have created, she gets to undo every one of her regrets and work out her perfect life…
