To be a successful trader/investor, it's critical that you understand your limits, and what's sustainable for you. If you work a 9-to-5 job, intra-day scalping isn't sustainable; it's better to pick an H4 or D1 strategy for your entries. If you're a fundamental investor, it's best to focus on long-term trends and position during quiet periods, as opposed to hopping on every new hot rotation. The key to succeeding in markets is staying in the game. And for that, you need a sustainable strategy. It's the same with the gym. If you want a good physique, but you're time limited, it's better to be consistent with a 3-day/week split than inconsistent with a bro split. Consistency trumps all.
