We observe, We listen, We sense and then we evaluate and develop a mindset towards that particular object, that mindset or feeling is refered as attitude. Generally the human mind generates only two types of attitude, one is positive and other is negative. But how could one know what his/her attitude is towards anything? And if it is negative, then how to solve it?
The answer is that you can find out the direction of your attitude height towards any object until the object itself tells you. And if the object tells you that you need to improve your attitude/ meaning that you have a negative approach to everything, remember there is nothing in the world that can help you change if you won;t believe in others, and there nothing in the world that can stop you from changing if you believe in yourself.
For the sake of yourself try to build up a positive side so that your attitude stays high.
