Two weeks ago I was looking at Apple (NASDAQ: AAPL) stock and thinking to myself, why in the heck is it going down so far? It was off $35 from its peak this year in January. I thought to myself, I need to invest because this is ridiculous. I--of course--didn't, and now the stock is up $15 from where I was looking to get in!!! Grrr!
 
Note to self: trust your instincts.
