Just to jump in here. Until I was 27 I was blowing it. Single guy in Asia eating and drinking exactly what I wanted - where I wanted. Now that I am 29 I have finally become a bit "mature" and I am able to save 2500 USD per month for the future/to buy an apartment in 2020. Do I regret that I lived my life when I was young? Naah! Not at all! But I would advice you to at least save 15-20 % of your online income every month. You will thank me later.
