Are you lagging around stuff that you don't really need? Maybe some of us are not even aware what we carry around all day. If someone were to asked what's in that big bag of ours, would we be able to say exactly what's in there?
I am one who does not want to carry big handbags especially everyday. It is only when I travel that a bigger one is convenient for it could carry all my immediate needs plus my mini iPad.
Moreover, I'm not tall enough for a big bag to be proportional to my height. Besides, I don't want to carry a heavy bag that may put pressure on my shoulders and distort my spinal column.
I have avoided carrying heavy bags almost all my life, yet my chiropractor had to make an adjustment because he found my tendency to lean on the left. My shoulders are not aligned, the left is slightly lower than the right. The years when I had the habit of carrying my handbag on one shoulder, must have taken its toll. Since I learned about this I always remind myself to alternately carry my handbag on both shoulders.
At a luncheon, I used an envelop purse while a friend beside me had a bag way bigger than her hips.
"How do you use a small purse, I can't seem to learn how?", she asked me when she saw what I brought along.
I'd say it's because of dependence on some items that makes us feel secure having them along all the time. But then we could trim that according to the occasion. Even though it is a hassle to change bags often, it has its advantages since we can review the contents thus giving us a chance to leave behind or discard what's not necessary.
Whenever I changed bags early on while I was still working, I often saw a stick of gum, a hard candy that is already sticky, receipts I just dumped in the bag after a purchase, used tissue I couldn't throw anywhere so I put it in the bag as well until I find a receptacle. Oftentimes I found a toothpick or two in it's wrapper that I must have gotten when I ate at Chinese restaurants; it would be funny though if I found a pair of chopsticks there, ha!
I believe however that things we put in our bags depend on our need. My daughter-in-law has the most variety of signature bags in almost all colors that she keeps changing to match or compliment her outfit. But when she had a baby, she got a Big Kate Spade bag so it can accommodate baby things including her wallet and cosmetic kit. On the other hand, my older daughter used a medium samsonite backpack for her baby things so it won't be awkward should her husband help her carry it.
I believe that whatever suits our needs is fine as long as whatever is inside are necessary and convenient to lag along.
