Who Am I ???

Thats The Question I used to ask myself and also another question what am i doing ???Maximum time my mind comes up with the answer that "i am a good person ." ..... just after that one question always pops up in my mind that "Am I ?" as i think i can't judge myself in that way it should be other way around.. and about the other question my mind comes with another answer says "To make this place a better place"....... i always try to stay positive but can't stay positive about my self estimation i always ended up in low confidence ... Can't find any reason may be i am not that good in studies or brain materials which is known as intelligence .... I dream about feeling dreams of my parents and family also mine.... but can't find a way out .... i want to work hard but laziness rules me don't know why i am writing this but i am writing .. like a totally confused......Yes thats may be the word to define me confused , day dreamer , lazy etc etc........
