They can, who think they can.

Personality of individuals vary. There are people who are hard driven and also who are flaccid. Yet, he who has strong belief in himself can achieve anything. Great men have left behind their footprints over the sands of time.Did anybody think of climbing the world's tallest mountain EVEREST? EDMOND HILLARY and TEN ZING NORWAY thought about it and through hard work did achieve their goal.To be successful, you have to grab the chance and go for it. "Think Different" was an advertising slogan created for Apple Computer in 1997 by the Los Angeles office of advertising agency TBWA\Chiat\Day .It stated "Here’s to the crazy ones. The rebels. The troublemakers. The ones who see things differently. While some may see them as the crazy ones, we see genius. Because the people who are crazy enough to think they can change the world, are the ones who do."
Let me relate an incident from my life that brings out the truth of the statement.Evey year in our school we did have annual sports.Student's participated in different events.I too did participate in the hurdles,but failed to grab a prize as because my rival,a close friend of mine had the knack of grabbing it.So in pain and frustration I used to kick up myself for several days.
Finally I made up my mind to defeat him.I took up all pain did hard work and kept myself fit.But this show lasted for a few days as my determination to defeat him was not firm it was mere folly.My father did send me to a nice coach who made me belief in myself.This man was kind,fair and true though sometimes harsh.I got trained under his guidance for a year and alas on the next annual sports I did grab the prize.
