Challenges, success, boredom and our brain

Our brain is a task performing machine, it likes to sink its teeth into problems and solve them.
We as humans, get a high sense of achievement, satisfaction, and enjoyment from solving issues.
When we are fully engrossed in a pursuit that we are passionate about, our brain doesn't wander, it doesn't flood us with random thoughts about upcoming events.
Its primary focus is on the task at hand.
Boredom, or lack of interest happens when the brain disengages and starts drifting from one subject to the next as soon as the novelty wears out.
As a result, we never reach the level where we start mastering any subject, the level where everything becomes effortless, and enjoyable.
When we stick to something long enough, we start getting over the initial resistance, and the subject studied loses its mystery, and starts revealing itself to us.
To get to that level, one needs to put in daily, conscious effort.
The work required to achieve a certain level of knowledge and mastery is almost the same for everybody, the main difference lies in the fact that some people have traveled the road leading to success multiple times. 

Armed with that experience and knowledge, they have developped a level of confidence and a system that helps them achieve their goals faster.
When we haven’t developed the necessary stamina that could get us to the other side of he hill, where the terrain is easier to tread, we are more likely to give up after our first vain atempts.
The training gear that never gets used, the language books that never get opened, and music instruments that never get played, all these are silent witnesses to our failed attempts at learning and developing and to our desire to evolve without going through the grinding initial effort needed for progress.
