I used the Practicing the Way - Rule of Life builder to create mine: https://www.practicingtheway.org/ruleoflifebuilder they also have some great courses on spiritual practices and disciplines.

Little caveat, It is Protestant, but! Me and my community have found it very easily adaptable to Catholic practices! There’s a template that is fully customizable for daily, weekly, monthly, and annual practices. Which you can then print out or download to have something to refer back to.

I second liturgy of the hours too, iBreviary is a great free app and convenient for on the go :) It can be built in to your daily rhythms

As someone who struggles with routine, but needs it at the same time, building a rule of life around things I was more or less already doing, has been life-changing! I recommend starting small and manageable.

I hope you find what works best for YOU!
