I've been told I walk like "I'm the king of everything". I assume it's because I study body language and the "alpha male" posture is the one I choose as my standart.
In situations I don't know if it's appropriate, I use it as a default and some find it offensive, some find it weird and others just say it's very elegant.
Walking / standing differently has to do with your psychology. The way you feel shapes how you walk, thus standing differently will also affect how you feel.
Of course, someone who functions neurobiologically differently is also going to have different ways of standing and walking, as it isn't clear for them what each posture represents in an implicit social hierarchy.
You can watch Amy Cuddy's Ted Talk to have a sample of this.
PS: Still, I like to count my steps wherever I go to measure distances and time taken to get there, If I can space them slightly to take less steps, I will. I'm always looking around and up while I'm walking, instead of regular "looking where I'm going". I like to go up stairs 2 steps by 2 (I'm tall so it's no big deal) and I like to walk as silently as possible. These are traits I choose to keep, I'm comfortable this way.
Peacefully,
