Sometimes things get tough at work or in life, sometimes it creates a domino effect into other aspects. A badly done project at work leads to a bad mood, unintentionally brought it home and it leads to an argument with our partner; then it kept us from sleeping at night and the lack of sleep leads to a bad performance at work. It turns into a loop.
Keep something small everyday, a 5-line journal, read for 15 minutes during lunch; something that reminds us of “accomplishment”. It helps when things get muddy.
