I'm one of those people who says they don't have time. No time to do X, to time to hang out with Y, no time to think about Z. However, I know that this a problem of priority rather than the amount of hours in the day. Calm blocks out short amounts of time (~7 minutes) which is short enough to fit most places in my schedule. Defining hard boundaries on the amount of time I spend meditating helps me relax during meditation.
Calm has helped me meditate wherever I want to. With headphones in and a seat, I'm able to meditate wherever I have my phone. I usually do it on the L to work (Chicago). It fits conveniently time wise and I'm usually able to find a seat, close my eyes and let go, knowing that the session will end before I reach my destination
Starting meditation seems hard because you don't know if you are doing it right. Calm helped teach me a posture and frame of mind that works for me so I can spend less time worrying about technique and more time focusing on myself.
Just my thoughts, hope it helps
