Well, Son, life is really nothing but a series of practice. What appears to us as mere practices are the real life experiences we get as well if we follow through whole-heartedly. What do I mean ?
If you continue to believe you will get full marks (confidence) and also continue to be diligent in practising daily till the day of the test (building your competence over time), then the results you get will not just be a practice but a real life event !
This also serves as a reminder to myself that the things Dad do, trading, exercising, family peace and harmony, etc are also a form of practices that I do daily as well. I must continue to sharpen my skills (competence) and my confidence will grow over time. Not by willpower but by the Glory of God whom I believe he is constantly watching over us, blessing us in all areas of our lives !
