Yoga Accomplishments and Challanges

Since I started practicing yoga over two years ago I have seen many improvement in my practice:

• My Downward-Facing Dog has greatly improved; my heels are closer to the floor. Even better: Heather, my Vinyasa teacher tells me my Down Dog is one of the postures she has noticed that has significantly improved.
• My Easy pose is much better. Specifically my back is not as rounded while sitting, though I still need a cushion or a blanket to sit on. This is something I notice all the time because, before I attended physical therapy and yoga, I was not aware that I had this problem.
• Forward Fold. When I started yoga I could not even get my finger tips to touch the floor. Now my fingers touch in the beginning of a practice and most of my hands are touching by the end of each practice.
• Tree pose. I still cannot balance on one foot, but I am getting better!
• Other postures. I am sure I have improved on nearly all my postures, but the above are the ones I and my teachers have noticed the most as improving.

I am very lazy and almost never practice at home. This is a big problem in my practice. I read somewhere that for the most part, the postures you hate the most are the ones you should working on often. There's some truth to this for me; I don't like these postures because I either cannot do them/do them very well or they are uncomfortable. Here are the postures I want to practice at home, and some of them I do not like to strike:

• Tree pose. Yes I have improved on this one, but I am still far from holding the posture for more than a few seconds.
• Boat pose. I hate it and cannot hold it for very long, nor can I balance the posture very well.
• Hero pose and advanced modifications: I'm too fat to feel comfortable doing this, but I can do it. I feel for my fellow students who have to stand on their knees when the rest of us are in the posture. Reclining Hero pose I cannot do and would like to; also Hero pose with my toes facing forward--stretching my soles of my feet under the pressure of my body (Sorry I don't know the name, but I call it Torture!).

Finally, not a Hatha Yoga posture, but Meditation. I have started on this and I hope to continue.
