I think yes!
I want to be able to practice first and second series relatively fluently. There is a lot to learn in the first series, but the second series is rather new to me and needs the most energy. To keep up a daily practice is the only way to learn all the asanas and to combine it with the vinyasas. In my case I need patience as the body learns slowly, but progress can be experienced (not every day,......).
Another thought comes up too: To dedicate 3 hours (including commuting time and blogging and chatting with yogis) of every day to my yoga practice shall be enough. There are other things in life that pleases me, too. Do it and then let go, I think. It needn't be that yoga occupies my mind all the time. What was, what will come next, how to improve this pose, how to improve the vinyasas, the breath are all interesting questions. But enough is enough. And yoga has enough room in my life now.
