When I worked as a teacher, I had to follow the timetable . When to enter that class, when to leave that class, when to go to the next class......and i was disciplined by the rules. 

After I retire, my life is more relaxed. I, myself decide what I want to do on that day. No rules I have to follow. All up to me. But after one year, I realise that life after retirement is more challenging. When I worked, the rules or people disciplined me but here at home, I have to discipline myself. Especially for the solat sunat and Quran reading.
