I think you are asking if there is a difference between 'to stay' and 'to be' in your two example sentences... Yes there is a difference. An article entitled 'to be' creative would appeal to anyone interested in being creative. For example someone who has always worked in a factory, but now wants to start a craft business. But there is good chance that people who are already creative might be interested in reading it. An article called 'to stay' creative would be aimed at an audience who are already creative, or were creative in the past but for some reason feel less creative now. Perhaps someone who has been running a craft business for a few years, but finds the pressure of the business means they have less time for their creative side? So the correct choice depends on your article and the audience you want to appeal to. Does that help? Chris

to be = become to stay = continue I want to be fit = I want to start becoming fit; I want to stop being unfit I want to stay fit = I am fit now, and I want to stay fit from now on. I want to be creative = I am not creative, but I want to start being creative. I want to stay creative - I have started being creative, and I want this to continue.
