Discipline is the key to success, not motivation.
Let me explain.
Motivation is what gets you started, but it doesn't last long unless you put in the effort and work.
Discipline is what drives your success. The practice you put in daily creates an automatic lifestyle, which sets your life in a way where you do the things you practiced without even thinking about practicing them. This cycle lasts a lifetime, and it creates success.
Discipline is what leads a path to success. The practice and work you put in daily creates an automatic lifestyle, which sets your life in a way where you do the things you once practiced without even thinking about practicing them. This cycle is long-lasting.
