OP, while being able to develop the kind of kavana and feeling needed to daven a 1 hour shemona esrei is commendable, in life we do not have the luxury of devoting ourselves so completely to a single focus. One of the greatest challenges in life is learning how to balance our many competing obligations, to fulfill each one of them to the best of our ability, without neglecting others. We need to work and support our families; we need to learn; we need to help our spouses; we need to care for our children; we need to do chessed in our communities; we need to look after our immediate families; we need to daven with kavana. The list is endless, and each obligation pulls us in different directions. We can’t to all of them all the time, and we can’t focus too strongly on any one of them to the detriment of others. A one hour shemona esrei is praiseworthy, if that sort of teffilah is your niche, but you can’t use it as an excuse to not do other things required of you – whether at home, work, or school.
Developing a proper balance is one of our hardest tasks in life; we never really succeed, but we have to try.
