It can be about something small, but having a moment of mastery, can be very encouraging.
Mastery is something I work a lot with during interactions with clients, and it is highly underrated in the way most people look at it. It can be as simple as effectively planning a schedule, asserting yourself in a fast food line, recognizing that the mistake you just made is not the end of the world or even just keeping that one pesky hair back in the bobby pin all day. There are many things we as humans can master.
Other moments are not so good, there are times when it feels like we can't do anything right, everything is hard, and that danged hair just won't pin back. But those are the times when it is best that we've built up a mastery in other areas. Really it may sound small and obvious but doing something well builds confidence, and at a moment when nothing feels secure having small successes means a lot.
So, today focus in on what you're good at, especially those little things that we don't even think much about... like bushing teeth, making breakfast, or not yelling at a customer when they are being rude. Things you likely already do but haven't acknowledged much in you life. Really just take a moment and say - 'I did really well just now at not farting in public', or whatever it is. You are likely a master in lots of things, take a moment and delight in your abilities!
