Worrying about intermediate series

Today was another fun try for the sitting-up-supta kurmasana, which is actually called dwi pada sirsasana in the intermediate series! Luckily the Teacher is not too tight about keeping it in the primary series.... it's fun to do something different, and just to ask is enough to get that fun!

I did up to parsva dhanurasana again (my max dose right now), and during all of the asanas of the second, I was completely out of breath and tired. I wonder why: in the primary series, I have learnt to take it cool, trying to stay zen, and after an intense moment, regain my peace quite quickly. Maybe I am just so excited about being in the second series!

After the class I discussed a little bit with the Teacher on the subject: how on earth can people do the whole first and then build up the second and still have energy and time for a "normal life" ?! That is really bothering me. Do I expect that I gain so much strength and speed that one day I'll do both of them with the same amount of energy and time that I do the primary now? Do I skip something in the primary, once I am further along in the intermediate? I guess time will tell. I still remember how the beginners' load (up to navasana) seemed A LOT in the beginning...
