I empathize with your problem of constant lateness and was moved to respond to your comment on Yoga Girl's blog. Ah yes, the lateness habit. I too once had this particular problem. As a kitten I was so excited by life, I wanted to do everything at once and unfortunately that meant that nothing was done well. I was often late to dinner and missed out on the best, juiciest morsels.
Things became easier for me when I began to practice Yoga off the mat. All of a sudden the teachings of Yoga that I learned in my classes were spilling out into my life. While studying Patanjali's Yoga Sutras with my master, Sri Swami Purrananda, I learned that one of the most important teachings is of Ahimsa or non-violence. This means non-violence in action and in thought. I began to see that my lateness was actually causing others discomfort. They were disturbed by my lateness for they have as many pressures and things to do in life as I, yet they could show up on time and began to become angry, resentful and grumbled under their breath. Furthermore I caused myself much suffering. Isn't it true that when you realize you are late your body, mind and spirit begin rushing and beating yourself up. The whole trip in the car there are a few choice angered words at yourself, at the traffic and maybe even at God for creating the traffic jam. This is violent thought, violence that we have self-created and can easily remedy.
So what to do? I began to put others' needs in front of my own. I thought about them waiting for me and the beating myself up and endless excuses I would make up on the way there. I began to get up earlier and meditate more. In meditation I set my intentions for the day and start the thought process of thinking of others first. It became easier and easier. And now I arrive early, and guess what? I have time to look around, take in the surprise beauty of a quick passing hummingbird, smell the honeysuckle, say hello to passersby-- things I didn't have time to do before. It is so wonderful not being late as a habit. I highly recommend it. I feel lighter with a great sense of accomplishment.
It is not easy to break a habit. In Yoga we focus on creating new positive habits. It is said, you need to practice a long time, without break and with enthusiasm.
I hope this helps you, my friend.
Let me know how it goes.
Remember the Yogic life is not a purrfect, it is a practice.
Om Sweet Om.
