R My Q.
I flag or write down where I was, so I remember (if im at work or a coffee shop); and I email myself all relevant links before I finish a day's work, so I can pick up at the same place the next day
Salom O Q.
I do my best to not lose my focus. Specifically with notifications on my phone. I've started to disable them from different apps starting at the time that my bedtime routine starts. I know the issue isn't the interruptions themselves but me reacting to them. & Personally, turning off those notifications helps me a lot.
I find it really hard to not get distracted, so i try to make my deep work session at the start or end of the day to avoid people/distractions
