Once the right motivation is in place, everything is possible. When the motivation is not there, even simple things become hard. Motivation is not something that other people can give us, but something that we can find in ourselves through using our rational mind. In order for that to happen, four different types of insights are needed to arise for the practitioner:
1) there is something that needs to be changed
2) there is a way how that thing can be changed
3) those ways are available to the practitioner
4) the practitioner is able to use those ways
Once the right motivation is in place, it is possible to systematically learn something new and move towards the desired results.
