I don't know if I'd call it hardcore but I'd just like to be better each day in everything that I do so that when I look back 3 months, 1 year and a decade I want to be mighty impressed in where I've come from.
I'll use your word for it "hardcore". What was hardcore yesterday is not hardcore today because it's become a habit.
Hardcore almost conjures up a feeling of trying to impress others when really we should be impressing ourselves.
I agree with biglifter's statement, it's all relative, there are millions of people doing it tougher than me, I owe it to myself not to be lazy, negative, defeatist and anything less than what I truly can be.
