How do you keep your relationship alive ?

My husband and I have been together 8 years now. We work for ourselves from home. It’s a good thing and a bad thing because we have too much time on our hands. I think it’s good for couples to be apart and miss each other a little. My husband is outgoing and tries to go out for coffee or even just walking downtown. I am not as out going, I try to go with him but it’s boring and very repetitive at this point. When we go downtown, we walk around the same stores, same streets... it’s nice but we’ve done too much of that by now... what do you guys do to keep things interesting ?
