"Time & tide wait for none!"
Many of us think at some or other stage of life, "kaash humne us samay ye kar diya hota"! But now you can't have that time back and do nothing as you could do at that time. Hesitation is one of worst flaws that a normal human being has. 
All those who are living their college life phase, please do remember that, this is the time that can never never never come back in your life, once you are out of this. You are single for 18 years atleast, married for rest of life, in-process for some years, but this college life is limited only for 3-4 years. Do everything and anything you want to, your hearts says what is right and you should take a chance. If you like someone, tell them before it's too late, (because if you don't say it, they are definitely not going to be yours :p, but if you say, there's at least a chance to get them :). If  you don't wanna cheat, don't do it. If you love being a shy girl/boy, be it that way. Do everything you like. Live your life the way you want it, with those you want to be, with things you wanna have...So friends, if you really wanna do something, do it before the time flies.
