How often we tend to ape others consciously or unwittingly. The fact is; we're like sponges that absorbs whatever surrounds them. This fact should not escape your notice.
It is absolutely reasonable to emulate ones we look up to, and that in itself isn't wrong. Too often many get too absorbed in fads, trends, and even lifestyles of celebrities neglecting their own ingenuity. Basically guzzling from the band wagon's tumbler then failing to 'drink from their own tumbler'. This then leads to all sorts of appalling idiosyncrasies, mannerisms, and personality traits.
In a nut-shell, stay true to yourself, emulate fine/praise worthy examples, and most of all Drink from Your Tumbler!
