Spin plates logistic / How do you make time ?

I was reading the Rational Male, and started to think how can i start to spin plates. I work in a 9-6 job, come home at 7pm, rest a little, eat and go to the gym 4 days by week. I am in a LTR, and I see her only on weekends, sometimes 2 days, but normally 1 day.

Beside work, gym and ltr, I try to read to improve myself or my career (im a programmer).

So, I am very curious,

TL;DR : How do you guys manage your time with Work, Gym, Studies and Plates ? How many hours by week do you expend dating plates or even texting to them ? Do you see your plates every week ?

Thanks.
