Those that aren't honest with themsleves and try to be someone they're not, are only hurting themselves with feeling the freedom of truly being yourself. Life only comes around once and people forget that if you don't live it now, then you probably never will. I mean that in a way that many people take life for granted and look back on how they lived a life full of regret because they were never truly happy with either what they were doing in life or who they were in life.
If you can honestly say you are being who you are then you will be happy. When you love what you do because you honestly love to do it, then you are being honest. When a person loves you and you are completely your true self with them, then you are being honest. With pure honesty, you will live a much more enriched life all around. Honesty is the key to feeling fulfilled.
