One of the biggest difficults in life is to manage growing your patrimony and income, when earning minimum wage and living in poor areas where opportunities are scarce, as is the money circulating in the local economy. Some hints that could be useful:
Get rid of addictions/habits: addictions or habits (in mild cases) are harmful not only for your health, but also for your finances. Cigarettes and alcohol are responsible for consuming a large portion of the income from individuals living on minimum wage. It's not that unsual to find people spending at least 1$ on cigarettes daily, what after 1 month will result in 30$ expenses, which could be going into bitcoin investment, for an example.
Choose carefully where you go shopping: some supermarkets are more expensive than others. Shopping on physical stores is more expensive than shopping online. Don't go for the first price you see on the labels. Search for promotions, try to adequate your demand for products to your currently financial budget in a way you don't spend all your money in the end of the month.
The impression which matters is the one you have about yourself: forget about boasting yourself to friends and suitors around. Live a realistic life and don't pretend to have a superior lifestyle in order to make people's eyes shine in front of you. There is nothing wrong in displaying some style, it's actually pretty good and satisfactory, but only when we can really afford it.
Doesn't matter how depressing is your day, never give up: everyone has their depressing days, but these days can't become a rule in someone's life. Don't feel pitty of yourself, don't blame your life and your currently conditions. Think it's just temporary and that an exit from this situation is reachable with good will, effort, hard work and a positive attitude with people around you. Sometimes opportunities come from where you least expected, so be receptive to the society in general, while being careful with potential abusers of every kinds.
It's hard and expensive being poor, so anything that you can do to build up a bit of a financial buffer will greatly help you. If you can buy products in bulk you can save huge amounts over time and you should pay particular attention to special pricing because product prices can vary widely. I've also seen some crazy behavior by people with low amounts of money who try to replicate what they think other people with money are doing - like buying takeaways which cost huge amounts compared with learning to cook your own dishes (ideally in large batches) with cheaper but more quality ingredients - you also cut out a lot of overly processed foods by doing this too. Looking after your health can go such a long way.
