In Ramadan I usually feel very sluggish and tired which means I do very little. But recently I've been doing a lot and being a hell of a lot more productive. I try to wake early and do some cleaning, do a bit of theory revision and studying for nursing (I rarely do this I always feel like an hour or two of work a day is me done for the day) Then I'll cook. The day goes by fast like that if I'm not cooking I got out to the library or park or just anywhere really.
I feel like when we do things with our days instead of making ourselves feel like we deserve to sit around because we are fasting, our day feels better lived and more fulfilling.
I've been doing this anyway but I've found in Ramadan it's helpful too.
