You have to make this whole flow a new habit, but then you will be for sure more productive.
This answered my question really well, because I don't really believe in "just trying". So many people here confirm it's efficacy, so I will just have to start doing it. I already started to read the book.
Thanks for the reply and for the suggestion! I will have a look at it. I like your clear answers, and check out your blog.
Glad it helped you. I` m sure you will learn something good while reading it. As someone stated lots is common sense but there are also some ideas which let you rethink certain flows in your life. Even if you don` t implement it 1:1 like described it helps to improve daily life management.
