Greetings @chbartist

You raise in this publication three aspects that we must develop and reinforce to achieve personal improvement, these being the following:

The first, focus on developing one activity at a time, allowing to improve efficiency, reducing failures or losses due to errors

The second aspect, not looking back, is not reviewing issues of the past,

And finally, accept the criticisms, which, we must review, and take what is necessary to allow our constant improvement
