Polish seo advertisement

I have never had such problems with an advertisement. I work in an advertising agency where I am responsible for billboards and slogans. I enjoy my work a lot as I have always been a creative and open-minded person. I work in an online advertising agency . He have many different customers from all around the world and I must say that I love this work. Sometimes it is easy and sometimes it is very hard to come up with a good advertising slogan but the project I am working on right now is for me a disaster. I work for polish seo company and I have to prepare a good or even very good advertisement project for them. The problem is that I do not know what should I do. I have no bright ideas and when I am trying to focus on the project my mind is starting distracting me. I really do not know what should I begin with as I have no associations with Polish SEO company. Normally when I have a project to do I can associate the name of the company with a certain picture or idea and I have no problems with coming up with good project. I am really good at what I actually do bit this Polish SEO advertisement is true horror for me. Of course I will not give up but I have never had such problems with projects and I really do not know what is happening to me. Or maybe there is something wrong with this Polish SEO.
