Why should we chase for the frontier?

In either businesses or academia, people should look outside and explore the frontier. This is not to say we should always chase the trend, which is one of the frontiers, but may not be your strength. If you want to work on one topic, you should explore where the literature is. Then you need to go to many conferences and talk with people working in this field.
We should have conversations with others, not only because we want to hear about others' contributions, but also because it is important to get news about the frontiers, which are not always within the scope of our eyes and ears.
We should learn the latest framework because having some exposure to the latest development is equivalent to having conversations with others. This will definitely increase the workload. However, if you watch the best players in almost all sports, the common thing is that they get the best training. Getting used to the best, scientific, and systematic training is an important predictor of whether you will be successful in the future.
So now we have a long to-do list, which will occupy our entire days. How to manage that? In order to have a conversation with others, you need to do work. In order to learn the latest progress, you need to do work. In order to learn the classic materials, you also need to do work. How to manage such a huge system of notes? I never tried it, but my guess is that you need to repeatedly refine your old notes.
In order to keep your state, the most important is to overcome your guilt. You may feel guilty or shameful for yourself. You may feel guilty for making some mistakes or miss the deadline. You may feel guilty and you don't want to feel for making mistakes. But that greatly hinders your progress on doing many things. First, overcome your bad feeling about yourselves or others and start taking actions. Second, to improve accuracy and make things straightforward, start with simplest cases, choose the tasks you can do, and cut all redundant activities. If you are not sure about whether you need to do it, do not.
