“Study strategy over the years and achieve the spirit of the warrior. Today is victory over yourself of yesterday; tomorrow is your victory over lesser men.” —Miyamoto Musashi
Sentou Kaishi means to start the battle. It is a war cry used by the Japanese.
Sentou Kaishi is all about taking action every day.
Katanakaji comes first. It is all about finding out who you are and what you want. But once you have forged your sword (it usually takes six months to two years), then you focus on just taking action. No more analyzing (too much analysis will hurt you), just focus on taking action.
That being said, Sentou Kaishi is all up to you. Do whatever gets you the best results. Do whatever gets you to take consistent action. Whether it's as simple as a to-do list you write in the morning or putting paper clips in a jar, do what works for you.
Personally, what works for me has been evolving (as it will for you). That's why I've rewritten this article 3 times. You can see my latest version here.
