Strictly speaking, master-level designations require par-or-above performance at tournaments of master peers within said category. I'll skip the details, but it should suffice that a personal involvement in tournaments and talking to FIDE masters, International Masters and Grand Masters will direct you in the right course. Even dedicated students do not achieve mastery because their efforts fail to address their weaknesses as a player. Find a qualified mentor in your area.
So, as you've guessed by now, there is no quick way to master chess. If you see a young chessmaster, chances are he or she has put in much work through dedicated study that probably includes at least 4-5 years of tournament participation, chess literature study, and yet more playing with computer programms and online. No one is born a chess genius. Some people may be more inclined or neurologically adept to take in the demands of chess, but there is no substitute for hard work and dedication, just like in most areas of life.
