​Reflecting back on our own performance can be very valuable as long as it is done with the right intentions. Too often people reflect back on a situation to beat themselves up about how they could have done it better or they reflect back and complain about somebody else’s behaviour or performance. Neither blaming yourself or someone else is useful for moving forward and improving things for the next time.
A friend of mine started 2017 still hurt over 2016 past performances. This article is great at reminding to reflect but ensuring to move forward.
