I agree. However there are many enthusiast focusing too much on how much money they can make, but instead they should focus on how much money they could lose.
Motivation comes from your trading 'WILL'. Our dedication truly decides our motivation which builds up with practice.
Trading while understanding both the aspects - potential losses and potential profits is essential for keeping realistic expectation from the trades.
There is no real way to effectively regulate the ups and downs that the market experiences. It can be a good idea to take a break, clear your head, and come back with more motivation to trade in order to avoid being utterly exhausted after a series of nonstop trading sessions.
Imo, the best motivation comes when you understand the why of your trading. The reason you are making trades. At every fall when you remember the reason you started trading you’ll not find it difficult to stand again.
