Premise: Have strength, have real technology. Those who lack technical skills are not very useful even with patience; they can only buy spot goods.

President's Mindset:
Successful people all have a standard skill, which is to 'forget the last moment'.
If you earn a lot, but one time you lose all the profits at once, at this point you need to forget the last moment because the lost profits are no longer relevant to you. The worst thing to do now is to feel anxious about having lost the profits you earned last time, thinking about high leverage.
Or if you have already lost a lot of money, that loss is no longer related to you. What you have now is only the current principal. If you always think about recovering your losses, it will only affect your operations and your mood, driving you further away from your goals.
