Just a word of encouragement for the beginners and also the in-betweens to advanced yogis. Sometimes when a pose or a 'situation' gets challenging, be patient. In the beginning it feels like 'impossiblity' but with endurance and will power to 'live', impossiblity could become a possiblity. Peeling away the hard outer parts till you get the nice soft mushy parts is the part I find most exciting. Patience over time will reap huge benefits than a quick fix. Discover the mind and body without rushing.
