2 Stop caring about how people perceive you. The fact is, it really doesn't matter. It's impossible to be yourself when you're caught up in wondering "Do they think I'm funny? Does she think I'm fat? Do they think I'm stupid?" To be yourself, you've got to let go of these concerns and just let your behavior flow, with only your consideration of others as a filter — not their consideration of you. Besides, if you change yourself for one person or group, another person or group may not like you, and you could go around in a vicious cycle trying to please people; it's totally pointless in the end, and it leaves you exhausted. However, if someone you trust and respect critiques aspects of who you are, feel free to judge (honestly) whether or not it is accurate instead of accepting or dismissing the critique unconditionally.
走自己的路，让别人去说吧！别人的看法并不重要，如果一直担心别人如何看待自己，就很难真正做到自己。
