A few induction techniques involve waking up after 4-6 hours of sleep (I'l looking at you WB2B, MILD, and WILD). I know that for MILD, you set the intention of waking up after dreams, but it's advised to set an alarm clock for the start. Eventually, one should be waking up naturally.
questions:
1. Is there anyone who was bad at waking up on their own, used an alarm clock for a while, and over time you got better?
2. Is there anyone who was never good at waking up on their own and always has to use alarm clock?
Any answers longer than a yes/no are highly appreciated.

Also, I've found how to not wake anybody else up with an alarm. I wrapped my alarm clock in a towell and it fit snugly next to my pillow, thus muffling the sound so only I can hear it. I can punch the snooze button through the towell, then unwrap it better to turn the alarm off for good.
