I am a catholic but I don't usually go to church. My reason is I don't feel His presence there, I mean, I don't feel spiritual thing during mass (with it's routinary activity). I have nothing against with catholic church coz i am part of it, but sometimes I don't think i'm growing spiritually in attending mass.
Sometimes, i feel more comfortable in my room praying alone. But i know i have to participate in a community to grow spiritually but i really find it difficult. Maybe the problem is within me, it's just i'm so confuse right now.
I really want to worship God in Spirit and in Truth but I don't know how... :-(
First off there are a lot of Catholic charismatics around, you might get lucky and find some in your area.
Secondly, when it comes to prescripted services and prayers, it is easy for them to become thoughtless routine. However, that doesn't have to be the case. Honestly, in my charismatic church, our non-scripted services often fell into a routine as well in which people just did what they always did, because its what we did.

thats human nature.
If you put your heart into the liturgy and actively engage your mind in thinking about what you are doing and saying, invest yourself into the service, it will become something more than routine.
God desires our worship to be from all areas of our being. With our mind, our emotions, our will etc. That means you need to engage those things purposefully when you worship. Its not always easy to do.
The phrase "worship in spirit and in truth" was originally said by Jesus in response to the question of WHERE we should worship. Up to that point worship services to God had to be held in the temple in Jerusalem.
So, worshipping in spirit is as much an issue of where, as it is an issue of how. What that means is this, the bible teaches us that God is revealed to us in our spirit. Our spirit is the portion of our being where we understand God, it is the portion of our being where God dwells.
We are often not aware of our spirit however, because our nature is that we focus on our soul and only see our soul.
The challenge then is to submit our soul to our spirit. To open the connection between our soul and our spirit so that we can worship God as he dwells in the temple of our spirit.
I'm still learning how to really do that
In prayer I would suggest two things. One is that prescripted prayers are a good discipline. They are good for calming the mind, disciplining the mind etc, they are good for training yourself to pray always.
Yet prayer should also be personal. Just talk to God as though he is there with you, because in truth, He is. Talk to him as you would a father.
