I would definitely like to try what Leo babauta is suggesting. Staring at screens reminds me, Over the past few months I have grown to realize that life is lived well when its lived with reflection. Progress is always better achieved with reflection. Work and good life in general is not going anywhere, till you spend time reflecting how things are. Sit quiet ponder, take stock. You can live life with out reflecting, taking stock, but be informed your progress, towards your goal, is a mere accident, nothing but an accident. It’s not necessarily about progress, it’s the essential time where you give the mind a break and let things soak in, feel the importance of things, separate the unwanted, relive and rejoice a bit, let the clutter settle to leave a cleaner and a fresh mind.How much time to reflect is very personal, varies with person to person. If its about life in general start with 30 minutes, or rather try 3-5 minutes for every hour reflecting the previous 55 mins. I am sure you are better off with out staring at screens, while reflecting.
