The book can be summed up as 'Be there where you are'. It's a good reminder to stop running in life and stop regretting about the past. Just open your eyes and look around, the life is beautiful.
The book mentions that when people get serious health issues only then they start to realise the present and finally start enjoying it. I'm just thinking can I simulate that feeling without getting health issues. Think about and imaging you have 1 more day to live, how would you feel today? And like that every day.
Overall book is written in very abstract way, which I found very hard to conceptualise. It has very few examples which would be very helpful to understand all those good sounding words.
