Saving mode

Who said that in order to enjoy and to have a great life you need to spend a lot of money? Well actually I think it's bullshit. Saturday I was out with my dear Italian friend Giovanni, I had good time and I didn't spend such a lot of money. I got the bus to go to the city centre, after we had a delicious kebab with drink in a Persian restaurant in temple bar and it was quite cheap. Later we went in a typical Irish pub full of nice people and I paid for two cokes only 6 eur. When we left the pub was late so that there weren't bus to return to Stillorgan. I could take a cab spending 14 eur but I had preferred waiting for the first race of the nite-link that it cost to me only 5 eur. I remember other time when I was to cafe en saine where the drinks are rather expansive and I used to pay drink to the girls, again, I used to return home by cab. No that time is finished.
After a talk with my dear friend marcello, I have understood I need to save money if I want to have something solid for the time I'll be old. He said that because how much I have earned in the last 9 years I should have two loft in Milan...Well that's true even if my salary is not so big, just a normal salary as software engineer. Anyway I have realized that I have dissipated such a lot of money since when I started to work. Another thing I want to stop to do is spending money in expansive restaurants in Dublin. I am scared about this recession, everyone could lose the job in one day so I feel I need to save money. I mean I don't want to be tight but I am really upset after spent 40 eur to eat in a restaurant, does it make sense?
I used to pay even with most of my female friends but I think that time is finished, why should I pay drinks even if we are only friends? Well maybe I could lose some friends in this new phase of my life but maybe they weren't really friends.
