Even if you're not religious do you give something up or try to do something positive more?
After new year I gave up eating after dinner but the last couple of weeks I've slipped back into bad habits and feel bloated and crappy. So I'll go back to that.
I try to encourage my children to do something extra rather than give something up. Or they give up something different each week.
I'm going to give up procrastinating at night time on mumsnet and get more sleep so no screen time after 8pm. And no evening eating.
I'll also make sure I get a bike ride in each week as had started cycling and was loving it.
I'm not particularly religious but was raised RC and the habit and desire to "better" myself during Lent has stuck.
