The accumulation of life is essentially completing your main tasks every day. If a person cannot stick to their main tasks, their life is likely to fall into chaos. However, many times we fail to complete our main tasks not because of ability issues, but because we are distracted by various side tasks. In this world, only a few people can steadfastly complete their main tasks every day. Most people are paying the price for their excessive positive emotions or daily negative emotions. Emotions themselves have costs; they are not without price. Therefore, we need to deliberately train our ability to complete main tasks every day. In fact, this skill is very simple: give up control and demands on others, give up others' expectations and evaluations of you, and focus only on yourself. If you can do these three things, your daily efficiency will greatly improve over time. Although it cannot guarantee miracles, it will certainly lead to significant achievements. Conversely, if you cannot do it, you will remain stuck in the mud, difficult to extricate yourself.
