I’ve recently read a few thoughts about plans vs. mission in the current situation. Although the post is in Hungarian, its message is relevant so let me share the gist of it as a sort of encouragement.
The post talked about how so many now feel there is no sense in planning in these unprecedented times because everything is so uncertain and subject to change in the last minute. However, the author pointed out that having a mission/vision is something that can keep us on track even in uncertainty. It is possible to take even small steps daily that brings us closer to our vision, steps that are aligned with our mission. Your plans may change, you may discard some of them and overwrite others but they will still be calibrated by your vision.
