When you say this,
I didn't find any single context where people can take some tips how they can improve in the career.. Your blog was based on a question, what you do in private time/ public time
I read that blog again. If you go through it carefully, you'd find "what is really important for your growth". It doesn't say about career, office, family or anything directly, infact for everything in a way. That relates to Career
I am sorry dear but please read it again
