Difference between 뿌듯하다 and 자랑스럽다? What is the difference between 뿌듯하다 and 자랑스럽다? From what I know, they're both related to being proud (of something) but could someone explain it a bit more, please. Thank you for helping again! :)

Which one should I use to say "two years"? When I want to say "two years" in Korean, should I use 이년 or 두년? It's almost always written as "2년" so it's hard to tell. Thanks for your help! (:
