Feeling demotivated
السلام عليكم ورحمة الله وبركاته
So I've memorised almost 17 ajza alhamdulillah. There are almost 2 juzz that are very weak and I have to keep revising. I have had a lot going on the last few weeks including sickness so even after I strengthened them they became weaker again when I left them for 2 weeks.
Im feeling so demotivated now thinking if I memorise more what if I suffer further sickness or other responsibilities that mean I cant revise them to maintain them.
Any advice would be appreciated.
JazakAllahu khairan
