It's hard at the start with nothing to your name.
Potential mentors will reject you because they don't know who you are.
It's not their fault
Keep trying and iterate until you find the ones who will take a chance on you.
I want to remember to pay it forward in future for those who seek my advice.
At least help them to angle their pitch so they'll be able to find better mentors than I am. Or link them up.
