Any good thing in life is never achieved by keeping one's self in the comfort zone. To be in a pure form, the gold has to pass through many rough-tough processes.
The basic and the most important necessity to achieve the goal is the enthusiasm. If you do not love what you do and are not dynamic, the effort no matter how much you put towards it is futile. Once you gain the zeal, half the battle is won.
What matters next is your mind power. Be optimistic.
There are many things that tend to push us off our track. We must be stiff enough in our personality to ignore all the negativities and move ahead with broad perception.
When you initiate, failure is irrefutable. It is through failure by which goals can be achieved. Let the failure not dull your zeal. Your power towards your goal is always greater than the domination of failure.
The fundamentals are something you need to inculcate in yourself to achieve your goal you keenly want to achieve.
