How many blogs are too many?

So I just started a blog for my church group. I was thinking of also starting another one to track my fitness. That would be alot of blogs to keep up on. I already have 3 before adding those in. I love to blog though its so much easier then writing in a journal. I have had friends print them out and make books. I think that is a good idea and I think I will consider doing that with at least my recipe blog. So it comes down to this do I have the time and energy to do 2 more blogs?
