Serious How much time on your PC per day

Before I set up my site, I was probably online/desktop for like 2-3 hours. 3- 4 months later of web design it went up to like 12 hours a day Figuring out WP and content etc. Now that's sorted its just a case of traffic and updating but i then decided to get into cracking for fun and so its back to around 10 -15 hours a day. eek! lol
