nadt... of course it does make you feel better about yourself...Sometimes it might change your entire life...In North America there is a show called “Extreme Makeover”. They take not too attractive (i.e. ugly), chubby woman, bad teeth, ugly nose, whatever...who has no good job, no husband, who is absolutely frustrated with herself and her life. They literally MAKE her over: skin, teeth, nose, ears, fat off, hair restoration.. i don't know... everything.. they meet her again in about 1 year.. to find out that her life has changed completely! FIRST (and very first!) she got a self-confidence, and as a consequence she got a good job, she got a good guy in her life, and so on....
Sometimes not only it makes you feel better..It may bring you a lot of money as well... All the Hollywood stars, singers and Models constantly changing and fixing something.. and i suspect, the more they fix, the more they earn after that..:)..i think it became a type of the investment. Invest in yourself and you get a huge profit out of it!..:):)
