Learning Yoga is one thing and practicing it everyday is a different thing. When you learn it in a school everything seems easy because the company you have is highly competitive and they keep practicing in front of you that encourages you to work hard and stay focused.
But the moment you leave the school you are on your own. And if by any chance your friends and family are not into yoga then you are in deep trouble buddy because no matter you wake up at 5 AM if the person next to you is sleeping then chances of you waking up decreases more than 50% and I bet my facebook account on this and by the way my FB account is priceless. :-)
Environment plays a big role in the development of the human nature and personality, this is the reason people study a lot in Harvard, Oxford and the MIT because the environment is highly competitive. There is no way you can waste a single day without studying. The same applies with Yoga practice. The same person who used to practice for 6-7 hours will find it difficult to practice for 1 hour.
Hope you find the company to stay focused.
