6 week old schedule

I want to start by saying I know that when you first start with a schedule it takes time to adjust.

With that said, I'm starting with a schedule for my son 6w3d and he did awesome the first day but REFUSED to go to bed and stay asleep past 9:30pm he did everything perfectly from 10pm the previous night(I know a dumb time to start implementing a schedule) to his 7:30pm feed/bedtime. (He had a bath at 6pm)

I'm wondering what are some tips and tricks you all have for creating and maintaining a schedule with your little people of all ages.

[He's more colicky without some kind of order so I'm trying to make the day as predictable as possible]
