Some simple tips for saving money:
-Use cash, don't buy on credit.
-Don't eat out.
-Don't buy coffee from starbucks/etc.
-If you want to get drunk, stay away from pubs/bars: your/friend's home is a nice, cheap and secure place to get hammered.
-Don't spend money on big house, buy a flat instead. Home is not an investment (unless you rent it away some day).
-Get rid of a car or two.
-If you really need some electronics/hardware, buy them used.
After you start to manage saving some money on a monthly basis, invest it. Nothing is worse than having money sitting and being eaten out by inflation.
Buy stocks, ETFs, mutual funds (vanguard is the best), bonds, bitcoins, (gold, silver).
You can also consider investing some money on personal education (books, audio books, classes, certificates). There's also tons of free information on the internet.
Best way to save money is to make sure that every week you only give out a certain amount of money so that you are able to save easier.
Most people just give out money until they see that they have to take it easy but then it is already to late.
