Everything around us has issues. Sometimes they are challenges worth dealing and sometimes they consume hell lot of time not worth the value of resolution. But it's very difficult to classify an issue into one of these two categories - worth the time and not worth the time. But, I have found an easier metric to do that. There are many people around us. There are some among those who consider living life without principles as sin, working off the rules as punishable offence and prioritise design of the system over the system that works . Markdown such people. They will help you categorise issues. Any issue, these people consider as of utmost importance and you are confused about it, just neglect such issue for time being. You can come back to it later!!
