You can divide your personal time into two parts, devote some time to deep work (high-intensity, undisturbed concentration), and do other things the rest of the time. You can even create "deep working hours" by deliberately creating solitude space. For example, get to the company one hour in advance, enjoy getting up early, hide in the company meeting room and so on. In the long run, your brain will form inertia. At this time, you will start the deep work mode, and your concentration will be unprecedented, so as to better complete the high-intensity work.
In daily life, start with small things, take everything seriously, and strive to do everything well. Stick to it, so as to overcome your impatience and panic, and finally achieve good results. The first is to form habits. Recording and planning will really help you deal with longer-term and more complicated affairs.
For example, we all know Ebbinghaus forgetting curve, 1 hour, 12 hour, 1 day, 2 days, 4 days, 7 days, so when to review it needs to be arranged through previous records and subsequent plans. The second purpose, which is also the most crucial purpose, is actually to know yourself and the upper limit of your time control. It is important to know the upper limit of your time control. If you don't know your time management ability, it's easy to overestimate your ability and often fail to finish the plan. After the last many failures, frustration will push you to a worse situation.
