To be emotional or not?

Some ppl say emotions are main thing in life whereas others say that being emotional is a hindrance to growth and mental peace. Even some ppl consider it as weakness. So what r pros and cons of being emotional or otherwise? What I think is that being emotional is very necessary if u want to enjoy the life to its fullest. But dont let ur emotion fool u. sometimes they r very deceiving and u get trapped in them. Be emotional but dont be blind. Actually it happens a lot of times that emotions blur our vision and we become biased. Emotions are like a spell when u r into it u cant know that its a spell and when u come out of it then it seems that u were fool. Sometimes we cant help it and we have to flow with emotions. Being emotional brings a major disadvantage that u get hurted very easily and that can steal ur mental peace. Best thing seems that keep ur expectations low but dont ignore other ppl's expectations frm u. I always want to achive proper balance between emotions and mind. I hope I will succeed someday and till that day my friends plz forgive me if I have ever hurted you. Thats all for now. Keep visiting and keep posting ur comments on my blog.
