How do you handle client feedback and revisions during the design process?

Professionally. Regardless of your thoughts on the revision the client wants it for a reason. If you feel it doesn't need the revisions then you need to be able to clearly articulate why, and the pros and cons of changing it. I think the biggest key is in the detail the client gives when the process starts. The more detail you can get at the beginning the less likely they are to need the revisions. Hope this helps.

Not taking it personal. At the end of the day, they have a vision and my job is to use my skills to realize THEIR vision for their companies or websites or whatever. If I missed it somehow, that's okay. It doesn't say anything about me being a bad creative. It just means I need to try again until I get it right
