Just found a very good advice from someone’s blog:
“You’ll find in your life that sometimes your great ambitions will be momentarily stymied, thwarted, marginalized by those who were perhaps luckier; come from money; had more doors opened; where college was a given, not a student loan; it was something that dad paid for; where an ease and confidence in life was almost a birthright. Where for you, it was a very hard climb. … That happens all the time.
Just because you come from nothing, you must not let that be something that holds you back.”
