How to break a routine?

I’ve found my life is totally routine; I work then I come home, usually go up the pub on the same evenings each week and do similar things when at home. I guess I enjoy going out, but only because it’s a break from staying at home, I like the people I go out with but they are convenience friendships, with two exceptions that I can think of. Has anybody else found them self in this position, changing a routine is easier to say than doing; I guess I’m just lost at this stage in time.
