Emotions

One of my friend says that to achieve something one should not be emotional about it.It may be true , as it fetches early success.Its like press that OFF button of your heart and just focus on the job.It may work for many, but sorry to say that I am not like many. It surprisingly never works for me.If I like something or someone I knowingly or unknowingly become emotional about it.Its strange....Its difficult....but i cannot help...May be I should just follow my heart..May be I should just follow the rule:The thing always happens that you really believe in; and the belief in a thing makes it happen!!!
