Tish nailed it. Don't be too hard on yourself or expect perfection the first 2-3 months, somewhere in that timeframe you'll notice a shift to "hey, I really do got this..." and it's off to the races.

Fully immersing myself was always the best way to come up to speed, one thing I always do though is block at least 30 minutes on the calendar for lunch. Even if all you do is stare at the horizon and decompress for a few minutes, you need the break. Going balls out for 10-12 hours a day every day takes a toll, long and short term.

Leave time for yourself, no one dies with an empty inbox.
