Rabbi Silber's Parshas Behaaloscha video opens with Rashi's question on why Aaron's mitzvah to kindle the menorah is juxtaposed with the tribal princes' dedication offerings from the end of Parshas Naso. Aaron felt sidelined watching the Nesi'im bring their offerings, but Rabbi Silber - drawing on the Baal Shem Tov and the Rebbe - uncovers the deeper lesson in Hashem's response: don't measure your life against someone else's, because every person has a unique shlichus that only exists through being fully yourself. Comparing your accomplishments to another's isn't just human nature, it quietly extinguishes your own individuality and your own light. Rabbi Silber urges listeners to trade the question "why can't I be like them" for "what can I do," and to build a life on their own terms.
Comparing yourself to others erodes your sense of your own unique shlichus, or mission in life.
Aaron's distress at being left out of the Nesi'im's dedication offerings came from measuring himself against them, not from any real lack.
Instead of asking 'why can't I be like that,' ask 'what can I do, who can I be.'
There is no shlichus that is better or worse than another - only different, each equally vital to the world.
