Perseverance, Focus, Discipline

had a brief chat with a friend from bangladesh just now, and i found out that he is trying to get a phd in japan next year...urayamashii....*jealous...
and while writing this, i am chatting with a friend, my ex-colleague...and he is also trying to get his phd, in australia..
in less than 30 minutes, i am hearing two of my friends, from two different country, pursuing phd, in two different country....amazing...
anyway, in between the men's talk here in study room, my bangla friend told me that whenever he is in despair, he sometimes come to a friend, from srilanka, that always able to inspire him. and the one he has always remember is that in order to be a SUCCESSFUL person, 3 things are mandatory: PERSEVERANCE, FOCUS, and DISCIPLINE.
this srilankan friend, has been starting the third one since a month ago. from simple things like going to sleep at 11, and wake up at 5. and then do some yoga.
i personally believe in those values. and i personally consider myself able to pass the first one, but not the other two. muzukashii...*tough....how about u?
