I struggle to give step-by-step advice on what daily routine you should have. Or work habits. Or exercise habits.
The reason is that these can be so personal to you that there is no One Right Way of doing things. Anyone who says that they do know the One Right Way is lying or misinformed.
Instead, try this:
Try different things one at a time and see each one as a short term experiment (e.g. 2 weeks or 30 days). After the experiment ask yourself ‘Was this helpful? What did I learn? Will I keep going?’.
Over time you’ll find Your Right Way. You’ll find what works for you.
Note: Sometimes things will change and Your Right Way won’t work for you anymore. That’s okay. Just go back to experimenting and start again.
