How do you stick to a routine each and every day?

Actually following a routine is better for me because it makes life easier and more organised. notneed to think about what should i be doing. I already have everything planned

You definitely can stick to a routine if you make a time table, or we can say maoe a todo list along with time mentioned on it.
Second thing is to plan your whole day, a night before.I mean before sleeping in the night, you should plan your next day.

I wake up everyday now remember that I have goals and that I want to be a better version of myself daily. Once I drink a glass of water in the morning then I know I'm ready for the day and check the list of other things I'd like to accomplish. It is always good to stay productive and remember not only your worth, but also your potential.
