if you think negative thoughts...
the negativeness that will flood your mind and your heart will attract all that is negative from the environment around you...you will be able to see and hear and pick out only the negative in everyone you meet, in everything you do and in all that you read. Every conversation will veer only to the negative...
In everything and everyone there is negative and positive - but when you are negative, you draw only the negative out of everyone and from every situation.
It's likewise for the positive...so there's a choice here...
