Today I am sitting on my desk with a pen and a notepad next to me and writing down everything I do and the time it takes me, so I can understand why I keep reaching the end of the day and not move forward with what I had planned for the day.
So, my conclusion is: on average for every hour I spend "working" 20 minutes are lost. From breaks, phone calls, random searches I do online, etc.
So, on an 8 hour work day, just around 5 are actually productive.
@kai the strange thing to me is that I can't do the focused time without the "fluff" :)
@hugo Shoot I'd be lucky to have even that much work done.
@devinprater This was in a good day :)
@hugo e quando precisas de discutir uma coisa rápida com um colega, e quando dás por ti passou mais de meia hora, e o resto das coisas na lista de tarefas do dia a ficar pendente?
@arturcoelho verdade. Isso e telefonemas que "comem" horas :)
@hugo a subtil arte de distinguir "longos telefonemas que podiam ser emails" de "longos emails que se resolviam com dois minutos ao telefone ".
@arturcoelho uma arte muito difícil de dominar.
@hugo thing is, tho, we need a break every now and then so we actually keep being focused enough and healthy, so those breaks still count anyway. 
@eloisa yep, I can't function without those breaks 😅
@hugo see? So, those breaks are essential for work, too. Thus, they count as productive time too. Just a different experience of what it means to be productive. 
I'm the most when I'm dreaming!
@hugo even that is extraordinary.
I'm good for about 3 hours of focused work. The rest is fluff.
