Though it is not easy for sure, everyone can do it for good sake. Anyone. Anytime. Anywhere. Anyone who self learn do so at their own pace. That gives self-learners the benefit of focusing on areas that they are more interested in or wish to understand better. In a way, it helps them specialise in certain details.
This practise reduces frustration, anxiety, or boredom; obstructions that normally beset students who attend a classroom setting.
In such situations, challenges and obstacles would not deter their drive to get things done; instead the challenges provide them new opportunities to learn, and/or unlearn to relearn something new especially in anticipating the unleashed new normal phenomenon, now & then.
