Always be you. There are so many people who don't know who they are, so in their efforts of learning to become themselves, they tend to emulate others who they admire. This has happened for a long time and will continue to happen.
As long as you stay true to yourself, there is no harm in letting others try to be you. You will always be you and there is nothing that they can do to make you be less of yourself :)
Yeah @evolved08gsr, it's nice to look up to some people, and try to be like those we admire. As there are people who are still discovering their passion and what they really want in life. People grow old not really knowing who they are and what really want in life.
