Success is determined by your attitude & response. If you encounter obstacles & hurdles in your endeavour take the challenge firmly..If you take an obstacle as hurdle in your endeavour you are doomed to be failure. Never make an obstacle as excuse rather make it your weapon to fight away the odds & to strengthen your commitment towards your endeavour .Another factor which deprives one of success is fear, fear of failure, Remember there is nothing to fear but fear itself. As long as you know you are not doing wrong & you are not hurting,to other, stick to cause.with firmness & belief. If you fear nothing, then there is nothing that can stop you from getting to the top.
