How do you know you had enough practice?

Buddhism is very vast. There are many ways in which we can approach the topic of practice, and Buddhist study. I have been practicing Buddhism for only a decade, and knew that it was my path since I was a small girl. Practices vary in intensity, duration and focus. Each practice is unique for the student and their level. Individually each person will find directly if they had too much practice, connecting with your teacher will help you to fine tune that which is causing the strain on your practice.
