If you do not work and start trading to earn a living, then trading will become your robot. To start trading and do nothing else, you need to devote a lot of time to this business. Everyone wants to stop working for the boss and start trading, but not everyone can do it, because it's not easy. What will you do if you lose money once or twice or three times. After all, do not forget that trading is a very risky business.
Your success rate in trading does not depend on how much time that you put on it. You need such time when you are just starting as a newbie because you are new to everything you are seeing and you need to know how to navigate through it but if you have mastered the act, you only need to watch your trade, analyse your chart and know what trade decision to take. A newbie need such time but not an experienced trader. However, to rely on only trading for a living is going to put pressure on you.
