Being At Home Everywhere

What does it mean to 'be at home everywhere?' Does it mean being comfortable at all times or at ease in all situations? I remember the philosopher Marcus Aurelius remarking in his Meditations that one needn't have a literal vacation if their mind is always in a resting mode in all places. In the same way, perhaps being at home everywhere is a metaphor for the acceptance of all situations, pleasant or unpleasant, without the expectation of needing to return to something simpler or 'better.'
   I think what is interesting for me is to ask the question "compared with what?" whenever I am experiencing vexations or having some doubts. If I am feeling dissatisfaction with the present state of things, chances are that I am transposing that experience onto a vision (conscious or unconscious) of how things ought to be. This kind of situation causes me to conflict with the present moment. If, for instance, I see the chocolate ice cream and see an even bigger chocolate sundae, I will constantly be comparing the first with the second and then concluding that it is less than the latter. But if I then take that same experience and compare it to something that seems less pleasant to me, then that former experience seems better. But then we can inquire into this kind of situation even further: even if I find that the second thought is more desirable than the first, does that necessarily mean that it's what I truly want? This is where the inquiry becomes more nuanced, I think.
   A person might see someone else and completely admire them, but I have observed in myself that this admiration doesn't necessarily connect with wanting to be another person. For example, I have often admired people who are popular and extroverted, simply because they seem to attract people wherever they are and never seem to tire of the company of others. However, if you asked me whether I want to be an extrovert, I wouldn't be sure what to answer, because there are so many factors behind being anything. While extroverts enjoy the energy of others, it's not always blissful to be around people. On the whole, I often begin to feel that I am who I am because this is in part what I can handle at the moment, even though I am always subject to change.
 From the perspective of contemplative practice, being at home might amount to going beyond comparisons and having an attitude of continual discovery. This is to say: whatever is in the present moment has never happened before, and it is worth discovering and being curious about it. This is quite different from comparison, which is often based on memory and tends to categorize things relative to others.
