Old boy , interstellar , and i saw the devil <| sep |> Graduated with ME degree from a State school in Texas . Took out ~ 15 k in loans and received ~ 15 k in scholarships . I was fortunate in that my parents paid the other 30 k . I paid the 15 k of loans off 6 months after I graduated . Some things to note I took a fieldjob and lived on expenses so I was able to put a boat load of my income towards those payments . Also , any extra money I earned went towards those loans . I had my fair share of fun , but that was after I made heavy monthly payments first . <| sep |> The thing about a mass transit system is that once constructed they scale fairly well by nature . <| sep |> Well , change that . <| sep |> You don ' t remember them after 3 months ? I have a bunch of my favorite books in my room on shelves , and I can remember the plot points and main details in basically 80 % of them . I reread because I forget most of the details , but I am surprised to see you feel that way . I think you may retain more factoids and useless knowledge than you are even aware of TBH , or at least I do .
