Do designers get tired of designing?

I feel tired of designing sometimes. I like it but after my 9-6 I want to come back home and relax or indulge in other activities but instead I have to keep working on my portfolio. I've worked for 2.5 years in the industry now but I still won't get a job in the industry based on my experience but rather a portfolio. I am tired of looking at screens all the time. Maybe I'm not able to balance things. How do people deal with this? Does it get better?
