Living on credit is fashionable. Indulging oneself is fashionable. Saving money isn't.
This is a pity, as it has much to recommend it. You have more peace in your life. The end on month is simply a date on calendar, rather than a countdown to next pay-cheque. Purchases born of necessity can be made comfortably. Employment becomes a career, rather than a means of survival. You can look your boss in eye, rather than dreading his gaze.
Why? Because you've saved up some money.
Take cringe-factor out of your life. Erase dread of small hours. Put some money in bank! You may not be able to increase your earnings, but you can decrease your outgoings. This has same effect as getting a pay-rise; more money for you.
How to save money?
Examine what you spend it on.
Then, erase fripperies.
Vices: drinking and smoking are habits that kill you slowly. Save up for your hospital care by giving them up. Your lungs, liver and family will bless you.
Gambling. Gambling is folly. There are only three games player can use skill to alter odds even slightly; horse racing, poker and blackjack. These take years of dedicated and expensive research to get good at. And you don't get rich. All others will beggar you quickly if you play them. The odds are stacked against you, deliberately, by those who own game.
Luck favours bold, special need, or those under protection of saints. Betting is not brave, it's a compulsion, and no god watches out for gamblers. Examine feelings that surround your impulse to gamble; you will find they eat away at energy of your life.
Food. There is food that nourishes, and food that enervates. The former is cheaper: fresh fish, fruit, vegetables, clean water. The latter is more expensive, more garishly packaged, and more poisonous: potato crisps, sweets, fizzy drinks, burgers. Consider that you don't fancy junk food if you are sick; your body knows it takes too much energy to digest, and does not nourish.
