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?
