First, it is essential that you begin with one skill that you can master, and that serves as a foundation for acquiring others. You must avoid at all cost the idea that you can manage learning several skills at a time. You need to develop your powers of concentration, and understand that trying to multitask will be the death of the process.
Second, the initial stages of learning a skill invariably involve tedium. Yet rather than avoiding this inevitable tedium, you must accept and embrace it. The pain and boredom we experience in the initial stage of learning a skill toughens our minds, much like physical exercise. Too many people believe that everything must be pleasurable in life, which makes them constantly search for distractions and short-circuits the learning process. The pain is a kind of challenge your mind presents—will you learn how to focus and move past the boredom.
