Practice does mean a change in habits, and in the very way of habit formation. So it can feel like going against the grain. On the other hand, where your habit has been to go against the grain, practice may feel like learning to go with the flow. First you have to discern the flow.
Wolverine asked, "Do you practice going with the flow?"
Raven asked, "Is that a practice?"
Wolverine asked, "What is practice?"
Raven said, "Going against the grain."
Wolverine asked, "Sounds hard."
Raven said, "Uphill."
