First off, please realize that the growth you will experience is from your continually saying 'yes' to the Lord; He will lead you to all Truth, and it is this acquisition of the Spirit that is the purpose of our lives.
So, the goal then is to help you be open to the Spirit. What helps me....and you are not me, so this may not work for you....is to try to concentrate on the meaning of every word in every prayer said, and every word of the Liturgy that is used.
Clearly this is something that is not going to happen immediately. It will take effort, and eventually the difference will be felt. And, once the indescribable sweetness of the Spirit knows you and you Him, He will recede from you. You may feel abandoned forever, until the Spirit returns. But, keep trying, because in this struggle you will help yourself and others.
Certain services may appeal more to you than others. So, go more often to the ones you like best! I love the Paraklesis and the Akathist, because that helps me most due to my spiritual immaturity. Compline, well...not so much, at least not as much as Orthros or Vespers. Also, make special efforts to attend services in honor of saints that seem to stick out in your mind. There is a reason this drawing or attraction is occurring, even though we may not understand why at the time.They will intercede for you, and help you!
As an example of the above, St. Paraskeve has always been a favorite of mine, maybe due to my eye troubles--I've always been drawn to her. Then, wouldn't you know it, the first Liturgy I performed solo as a celebrant just so happened to be on her day!
So, where I'm going with this, is to pray with fervor and concentration. Be joyful in your peaks (of course, who wouldn't be joyful then!), and be persistent in your valleys. That is how you get the most of your time in the Temple.
