When I worked outside the home and I was required to report to work at a certain time, I set an alarm clock. But now that I work from home and can set my own schedule, I don't use an alarm clock. Also my alarm clock broke! LOL.
Yes, I usually set an alarm on my phone before I go to sleep.
Setting an alarm clock helps me to wake up in the morning on time and start my day. It also helps me to stick to my schedule and stay on track with my goals.
I used to set my alarm at 6:30 am when I am working on the office. I sleep earlier than 12:00 or 11:00pm and wake up in the stated time. But now I haven't used my alarm clock in my phone anymore
