Do you think the morning routine decides the productivity for the rest of the day?

I think a routine around planning out your day (or even week) is probably the most important factor in boosting productivity. Even better than a morning routine for me is an evening routine. The last thing I do each day is plan the next day. I check the tasks I already have scheduled, add new ones that require immediate attention, look at my calls/meetings, and then timeblock out everything. Doing it the evening before means there are no surprises when I start work the next day. No big meetings or projects I forgot about. No big blockers. I can just sit down at my desk and get to work.

Absolutely yes, a morning routine is a great determinant for the rest of your day. Your breakfast, the time you wake up, and your day plan play an important role in deciding your productivity.

I don't think so that morning routine is deciding factor for productivity. I am not a morning person but on most days I am highly productive. If morning routine becomes deciding factor for productivity then poeple working in night shift would be the least productive ones.

I do think that planning your day in the morning and having everything in order before starting work is important for productivity.

1000%! If I don't have a coffee, read and work out, I feel like my whole day is lazy.

For sure! If my morning starts early and energetic then the entire day is productive!
