I used to weigh on a rigid schedule. Monday mornings were like exam day. Weigh myself first thing and then write it down. Thursday mornings were unofficial, I'd weigh myself but not write it down. It's a bizarre little ritual.
Now I've given up the Thursday morning unofficial readings. I still weigh myself most Mondays but not always! So I'm getting better at not giving too much important to the scale. It's a hard break to make I won't lie. I feel oddly attached to my weight journal. I can look back to any Monday in the past several years and tell you exactly what I weighed. So for example I know that the last time I wore a particular dress I wore it for a friend's wedding in June. Now I go back to my June log and see what I weighed that month... and now I know whether or not I can still fit into that dress lol. Gosh that is bizarre isn't it lol.
