Physical appearance changes how others see and relate to us - how important do you think it is to spend resources (not just money) on enhancing it? How much do you think it changes people's opinions of each other?
No doubt that everyone would agree physical appearance of an individual is to how one perceives themselves and how we perceive others, but to what degree we should care about our looks really comes down to our own morals and ethics also why you value your physical appearance.
We all hear the cliché, its the personality that matters, not the looks, but I personally feel that to be a pressure to adhere to. In social settings, I'm not really the greatest at speaking to other people, and this really deems me insecure about my character. That's why I like to dress neatly and concisely, in comparison to casual tracksuits and singlets, I think its a way to redeem myself
I have a twisted mind.
That doesn't mean that I spend hundred of dollars in clothing and makeup, on the other hand I barely wear makeup, but that's just to tell everyone that I am a simple person. If someone does spend a lot money on their physical appearance, I got nothing against that, as long as they're content with themselves and not going broke, then go for it. They just want to send the message that they value their looks and like everything refined and polished. That sounds pretty good

but you need to make sure that your physical appearance doesn't take over your mind, or you'll be losing yourself, your self respect and the respect from everyone (unfortunately) around you.
I think it comes down to
how you want to portray yourself and your self value. I'm not against people that get plastic surgery b/c if you think about it, there must be a good reason why they got it, they are people that can think, why would they put themselves in that pain and long procedure unless they have a reason. is the reason valid or not, that's not for me to judge, but if they do decide to get plastic surgery for insecurity, then I have to blame the people around them or the media for bringing the size of lips, nose etc. to attention and not the individual who has a heavy weight on their shoulders saying their ears are disproportionate.
Also, I think people just like things that look nice, that's why people with aesthetically pleasing tumblr pages get the most followers. Even when you come home, everyone likes coming home to a neat and tidy house, but the effort to make it neat and tidy, heeheee, that's another story. Just like meeting a new person, whether you like it or not, first impressions happen in the first 7 seconds, so choose wisely what you do. I think subconsciously, when we choose to dress nicely, its a calculative move.
So, I think focussing on your physical appearance is really up to the individual, but they need to make sure that their other worldly activities don't get neglected.
