We all have them but it is how we use them which is relevant. People with strong opinions can be rather daunting to say the least. They fail to see other ideas or thoughts.
The same can be said for attitude. Some people can walk and talk with attitude while other people deem themselves not worthy to do so.
Passion is often confused with opinions and attitude, but it tails into a different light. To be passionate about something draws in people who bask in the ideals being presented.
Opinions and Attitudes are great in moderation and I have learnt the hard way to balance them accordingly.
