"Those who abandoned their dreams, will try to discourage yours."
There are a lot of these types of people in this world, and many of them don't even realize that they do this, since their own loss and self-denial takes place at such a deep level. The more convicted you are in following your path, no matter how risky or outside of the norm, the more these people will be drawn to you, often crushing your spirits and ambitions as if their life depended on it. But in a way it does. Because if you succeed in following your path that's off the beaten road, it means that their whole lives of playing it safe and denying their inner voices may have been a lie, and a wasted life is the hardest thing for a human being to face.
Be mindful of these people, but don't engage them. Just know that when they come out of the woodwork, it is because you are following your path, and let their discouragements and projected fear give you more strength and perseverance in being true to yourself. At the end of the day, you have only yourself to answer to, so make sure whatever you have to show and say to yourself is something you can live with and derive pride from, not what others can live with and feel safe with.
What makes you unique is what makes you strong, and what makes you strong brings you closer to your own personal Truth and purpose. Don't let the weakness of others prevent you from expressing your true greatness.
