As a genuine practitioner,

one has to be aware of factors which decide how the practitioner will be able to achieve success in respective goals in terms of spirituality.
Once one embraces the journey, there are many issues which the practioner has to know as much as one is able. Many tend to overlook why we have to change our bad habits.  Changing our mindset is the most important to the progress in our spiritual growth. We need to begin with a new approach to the ideas and learning about Buddhism. Moreover, holding to our old and illogical mindset will harm our progress.
And also we have to be brave enough to accept changes and be adventurous enough to apply new skill and wisdom for the betterment of our spiritual gain.
Therefore, for the practitioners, listening, contemplating and applying all those are very essential, but without changing our mindset and be courageous, success in spiritualism is very difficult.
