In any learning situation, in order to advance from know to unknown, one may face new and awkward challenges from time to time.
Most of us hesitate when asked to perform an unfamiliar task as we afraid we lack the knowledge, techniques and skills to do it properly.
Do the best you can, as the attitude is the one that really counts. You may be surprised or amazed at what you are capable of.
By trying your best and putting your heart and soul to the new challenges, it could lead to some new finding or some break through.
It is the same for most of the new discovery.
You will master new knowledge/technique and skills to go through the difficult path if you have the right attitude.
The same path which looks difficult to cross will become managible if you are willing to put your heart and soul in crossing it.
