Your priorities are right for YOU, at THIS MOMENT in YOUR SITUATION, which is what matters, right?
People grow up, evolve, change careers/hobbies/lifestyles/tastes/homes/country ALL THE TIME. You might be crazy about bags today, and about collecting paintings, or riding, or philosophy, or singing tomorrow. Just as there´s no one-size-life-fits-all, due to globalization and extreme social and professional mobility demands nowadays there isn´t even one individual who can claim their own life is set in stone and s/he will stay in the same job/home/country/situation, not to speak of something as subjective as their tastes/hobbies/needs, even within the next five years (unless s/he is a hermit living in a cave in the desert, or a gazillionnaire entrenched in her own private island paradise, of course). Those who do are often kidding themselves; so, if they can´t even predict where, how and with whom they´ll be in a few months or years´ time, how can they even try to predict what´s best for somebody *else*? Your life, your terms - as long as you don´t harm anybody, starting with yourself
Like you, I´m single and child-free (didn´t plan it, just turned out that way and, with hindsight, it´s been serendipity, and decidedly for the best in my case) and enjoying my mobility and surplus money any way I like (a bit on bags, a bigger bit on gardening and my dogs, an even bigger bit on travel, and most of it on books). Some place having their own family as their top priority and accept to sacrifice other things to have it, others are devoted to their job to the exclusion of much else... or as the Vulcans would say, IDIC (infinite diversity in infinite combinations).
The only possible problem is when the top priority "eats" all your time and energy so much that your other, also important life areas (health, family, social life, spiritual life, personal development, etc) are shortcharged and the imbalance makes you suffer. Or when it turns into a wasteful, dangerous addiction - or when the top "priority" is an ersatz (or an excuse) to keep unsolved issues at bay and shirk unpleasant tasks and commitments. Like, for instance, spending all one´s free time mindlessly shopping "because it is vitally important for my job that I find the perfect blouse/shoes/purse/hairstyle" instead of spending an hour a day on something actually important to one´s job like learning a new language or computer skill. Or seeking to fulfill one´s emotional needs with proxy objects, pets, or people to compensate the perceived "shortcomings" of one´s family, SO (or lack of SO) or job. Not saying at all this might be your case - just throwing some generic food for thought into the arena. Sorry for the rambling!
