I spend all day on my laptop, unhealthy/obsessive?

Firstly I'm unemployed. Secondly I spend this time search for jobs and applying for them, I applied to 15 jobs today which involved registration/cover letter/cv etc. I'm also planning to do a masters next summer so I'm going through postgrad courses with a fine tooth comb to see what they would offer me. Do you think I'm spending too much time on my laptop?
