passion...less

Was looking for some life advice from anyone willing to part with it. Im a 26 yr old family man with 2 young kids (4yr old and 3 month old), and have found that besides family i have no real passion on drive in my life. I used to surf and play footy as a younger lad, but with family and work commitments i just cant do them enough and find when i do im not enjoying myself as i remember... Basically i feel like im floating through life with no real goal. So my i was wondering if anyone had some sound advice, have been in this situation before, maybe a good book to read. Any reply would be appreciated!!
