Is it just me ?

I want to be a charming person but the incorrigible problem i am facing is mY deFaULt SeTting is thinking negative

Like if a person comes to me with a idea.... I would INsTed of inspiring him i would start saying to him reasons why it may not work and what are the potential challenges while I in my head act like a so called pragmatic and PruDenTiAl person i just end up perceived as really negative making me less of a magnetic person
