Biased towards opinions

I am usually biased towards my opinions and believe that I am right all the times which is wrong. I frequently have disagreement with my team members. Sometime, I am right and many a times I am wrong as well. My biggest challenge is to identify the correctness of my opinions.
After I am proved wrong, I lack confidence in my abilities for a few days and then become over confident afterwards. I want to be balanced in my life in terms of decision making.
