What is a good strategy / approach to get back to routine after a long holiday?

I think you slowly start to get back to your old routine on your own. Took me a 2 days to get back to working ways after coming back from a 10 day holiday..

Begin your first day back with smaller, less demanding tasks to ease into work mode gradually.

Use your calendar to schedule your week and make a plan for what needs to be accomplished each day.

Begin your workday early, so you can get more accomplished before getting distracted by other things.

Schedule short breaks throughout the day to refresh your mind and stay productive.

Set achievable goals for each day to avoid feeling overwhelmed.

One rule : go at your own pace Don't try to do everything in one shot Do things gradually and be gentle with yourself The goal is to be consistent, not to be perfect for 10 days and then give up

Clean up your workspace and make sure everything is organized, so you can work more efficiently.
