Time comes to me in two ways.
The first is external time. It's the amalgamation and harmonious synchronization of all schedules, appointments, expectations, obligations, routines, standards etc that the everyone in the world operates on as a whole. For specific examples, birthdays, anniversaries, time you have to be at work/school, bus/train schedule, things like that.
The second sense of time is internal. It's formed out of your personal destinations and situation, your fate. Some examples are your death, emergent problems, nostalgic reflection, ETA of where you're going, emergencies or crises(or lack thereof)...
I feel little obligation towards the external sense of time because I don't understand why it is necessary to be synchronized. I feel everyone has their own personal life and situations to go through and this is complicated enough without the external world imposing on your state of mind. Because of this I tend to always be late or absent to appointments. I can easily drift off my sleep cycle. I never hurry to do things, unless it is of critical importance. I forget or disregard expectations and dates, and I don't like to work when everyone else is working. I prefer to work, live on my own time.
