Happy at Job #2

I wrote in initially on how I am frustrated at not knowing how to be happy at my job .

I’m currently fustrated at my job since each time I come up with a project to work on, I’m told no by my boss or that he’ll not use it to make any business decisions because of X reason. I’m also frustrated that I am not growing at my job and I’m only working on one project which for me is nothing.

Does being happy at your job mean creating an intentional model with the feeling happy for circumstances where I’m currently feeling fustrated ? For instance, I’m not happy with working on only one project, I’m not happy that the projects I’m working on are not being used or being told I can’t work on a project, and I’m not happy I am not growing.
