It's not likely that I'll stop because of lack of time, just as I won't stop eating because of lack of time. But meditation and other pracitce requires an environment which I won't be disturbed. If I travel with my friend(s), it will be very annoying to them if I suddenly said" hey, I am going to meditate, so please don't disturb me for 20 mins!".
Now I enjoy 2 good sitting practices, both at home. That's very nice. In the future, or in any circumstances, maintaining the morning practice is still easy-- just wake up a bit earlier. But the afternoon one is not. In the coming year, I may be out from 9am to 9:30pm on week days. I'm not sure whether I can find a comfortable place to meditate without feeling rushed, and without making it too close to my dinner. The other option is to meditate at night, at home, which is also difficult to control sine my brother, whom I share a tiny room with, has a very irregular sleeping time. The room is so small that if I mediate, he just can't get in or get out.
For Americans, it would be easy as your houses are very large. Here the averge house is below 400 sq feets, for the whole family.
