Fear

Something which you don't want to be with you but it will always be with you whenever you don't want that... this is called fear...

Fear can be a boon or bane to us depending on how we take it...

Sometimes fear will lead to our failures and sometimes that fear itself will lead us to Victory depending on how we take it...

Sometimes when we fear of doing something we either won't try or we try with more precautions.... The one who doesn't try will fail and the one who tries will win...

So have fear but take it in a positive way... :)
