Would you like to know your future? If your answer is yes, think again. Not knowing is the greatest life motivator. So enjoy, endure, survive each moment as it comes to you in its proper sequence -- a surprise.
Don't show a friend your gift, or your bag of money if you still want to maintain your relationship, but if nay, go on, and all you'll see is hate and jealousy, and you'll fight with him in the street like a dog and all you'll feel is regret.
If I knew then what I know now I guess it'd make no difference; Fate's sure in the way somehow. What's important is the essence. Although we still have free will We also have a whole lot to deal.
