How to be postive

I got a job . I think I had to rejoice and be happy . I can learn alot of things here . I still miss lucky alot . I think he is gone four months . Yet the wound is just fresh . I hope my family will buy me another lucky . I don't know . I can't help myself comparing the past with now . How higher pay I used to have . How my boss will provide me with everything , And there is 2 guys helping me out . Here ....There is like none .But I get to learn in another way . I know I should be always content in whatever I had . My working space is daam small . And there is no stationary here . It is like downgrading from a 4 room to no room flat .
