How can we live a life that focuses on spiritual practice?

A student was inspired by us retreating to a live in the bush to focus on our spiritual practice. She would like to take a similar step but, finding the preparation tough, wrote the following:

“I find myself working 8am-6pm to build a strong financial foundation to retreat from this path to spend the majority of our hours on spiritual practice. However, I’m concerned I will be ‘behind’ in my spiritual practice by the time I am truly able to focus on it. In the meantime I am preoccupied with working in order to move towards enlightenment. It feels completely incongruous to what I’m trying to achieve. Grateful for your thoughts on this.”
