In yechidus the rebbe told me to do something that at the time i felt i couldnt follow. I dont know how i had the nerve at age 18, but i told the rebbe that i couldnt be a lubavitcher then as i couldnt follow what the rebbe advised. The rebbe answered " you are 99% lubavitch and need another 1% to be 100% lubavitch". I will never forget this
