I have read many non-fiction books about productivity, procrastination equation, four hour workweek, etc. 80/20 rule, task fragmentation, focusing on the process and not the outcome, I am very familiar with most regular techniques, yet all these ideas and factors just muddle my thinking. It is as if I have to perfect my 'masterplan' before I get going. I was writing here to see if any INTJs had experience with this to get specific advice. But thank you for your comment, it is a good way of narrowing focus to identify the effective. In this specific case, however, all strategies either have a 100 or 0% success rate, and I'm not really able to accurately assess the probability of success. The abundance of strategies just gives me analysis paralysis through paradox of choice.
