Fr. Nicholas made some very good points, reading is very important. This is true especially if our priest (or the whole church) is not setting the best examples in piety; the saints are our "rock stars", our sports heros, if the only example we have before us is our parish priest and he is not a "star" and maybe even a bit of a failure, then I think it to be very difficult to be "better" than the example we have before us - and that example might be one of failure. That is, unless we read about the Saints and Orthodox books in general. Of course no priest is perfect and so I do not mean you should search the globe for a guru, but I have also seen some very discouraging priests, and I don't think it is healthy to be around them either. It seems in my reading and study, saints have spawned saints.
There are also some books which I don't know if your priest would recommend, but they are very good and for the most part Orthodox in thought; and they may be "interesting" enough for your daughter to read and perhaps give her that spark - C.S. Lewis' "The Screwtape Letters".
It is very good that your wife at least will go to Church with you and the same for your daughter. I know of families that have bitter struggles on where they will go and it is a constant source of hostility for the entire family. One husband even has gone so far as to feed their children food intentionally so they cannot go to communion! There are women I know that struggle all the time, and with 3 and 4 children; sometimes you look at them and they look like death warmed over, and you cannot do anything but think these woman are absolute warriors! I admire them so much.
St. John the Chrysostom says that if you want to save your wife then first save yourself. If your wife sees the transformation in you and the change in your heart where anger is turned into love and you never stop giving yourself, first to the Lord and then to her, if she wants this for herself, heaven on earth, then she will naturally follow. So I would encourage your family when and where you can without pushing them, the Holy Spirit really must awaken their hearts and pushing them only hardens hearts.
But most of all, work on yourself! If you have ever flown in an airplane you may have noticed the safety instruction they always give: "in case of loss of cabin pressure, secure the oxygen mask on your face first, then assist smaller children and others around you." (or something like that). Your whole life has to be re-centered and re-orientated, and like Fr. Nicholas mentioned, you will go through the initial zeal, burnout, a second-wind, a third-wind, but don't let yourself fall into a state of satisfaction. One youth recently told me that if we are not building our house in heaven we are most likely destroying it. If you don't like what you see in your house, it is a reflection on your own holiness, therefore, don't fix the symptom, fix yourself.
But doing this is hard if we don't have the right motivation! We must have come to recognize Christ's love for us so that we can in turn, love Him back, and there we have the motivation for everything. How does one come to love Christ? Well there are of course many thoughts on this but I would say is coming to know the Truth; if we know the truth about ourselves and about Him, and this world, we cannot but help love him!
And so everything, ever step of the way is done with prayer. If we don't pray then we are starving ourselves of everything. Everything should be done with prayer first. When you get into your car say a prayer, and when you arrive, say a prayer.
I have rambled mostly, so forgive me for the disjointed thoughts.
