I meditate for 10-15 minutes daily after waking up in the morning. I use mindful meditation -- where I just observe my breath and if my thoughts starts wandering I just say "that's nice, but not right now" and let it go and focus back into my breathing.
For learning meditation, using apps are great. Headspace is a great app that I highly recommend. Calm is also good (already mentioned).
Do you use meditation? What is your process and what impact did you experience?
Yes. There's a great section on it in the book Pragmatic Thinking and Learning, which I recommend to everyone.
I also strongly recommend Tai Chi, especially for people who struggle a bit with sitting still and meditating. I am nearly 55 and have spent most of my adult life in front of computers. Tai Chi has saved my wrists and back. I use basic Tai Chi moves to help trigger a meditative state if simple breath observation isn't working (my monkey mind is an entire tribe sometimes!).
