I just want to have fun :D
Now here’s a life's summary of one of the greatest sword duelists to have ever lived, Miyamoto Musashi (1584-1645):

"From one thing know ten thousand things"

Known by several names, Miyamoto was considered as Japan's greatest swordsman and perhaps the world's greatest sword fighter. He was also an author and philosopher who wrote The Book of the Five Rings, an important work on philosophy and tactics. Miyamoto fought and won his first duel at age 13 and spent his life wandering Japan and dueling. After defeating another famous swordsman, Sasaki Kojiro, in a duel in 1612, Musashi started his own school of fencing. Despite his violent life, Miyamoto enjoyed a peaceful retirement in which he became a famous writer and died in bed.
