People with a positive attitude and outlook might get a positive result and might get a negative result. While it would be wonderful to be able to say a positive attitude will result in a positive result 100% of the time, it’s simply not always the case.
People with a negative attitude will almost always have a negative result because their negative outlook will adversely affect the outcome.
You can’t guarantee a positive outcome with your attitude but you can pretty much guarantee the negative one.
Have a great and positive day!
