How many times have you bought something because someone else told you it was cool?
You bought a pair of trainers because your favourite sports player wears them or you bought all your clothes from a certain department store in the city because all your friends do.
Sound familiar? This is okay as long as you realise that you are most likely paying more money for an image, and more money does not always mean better quality.
Your favourite sports hero gets paid a lot of money to wear his trainers, and to tell people like you to wear them.
Do not rush into a decision just because everyone else tells you to.
