Having good teachers helps, as well as encouragement along the way. In addition, I assume there’s a willingness or a certain drive to see it through– maybe not to master it, but at least to increase proficiency and understanding.
The assumption being made is that whatever the task or activity, it is something a person was interested in trying in the first place, something seen as worth doing. If there is true desire to gain knowledge and get better at something, the desire itself will be enough motivation to weather the moments of discouragement and sustain the effort.
