First steps are to get as good a job as you can, work hard and keep looking forward for other opportunities in your company but also at other companies that can help you climb the ladder
Make a budget and track your spending. I use Yolt, an app which can connects to most online banking and groups spending by type. I can set a budget there for various sectors (groceries, coffee, nights out etc) and it alerts me if I am nearly overspending in any one of them.
Set up an automatic payment to a savings account on the day you get paid. I would recommend two actually - one payment to a easy access saving account where you put money aside for nice things you need to save up for like a holiday. And a second payment to an ISA account which is NOT TO BE TOUCHED unless it is a real crisis OR you are buying a flag and using it as a deposit.
Pay into your workplace pension. Your employer should contribute something - ideally you pay as a % of your salary half the age you were when you started. So if you are 24 now, aim for 12pc but that includes employer contribution so if they pay in 6pc, you pay in 6pc.
Take your own lunch and snacks to work 90pc of the time. 10pc eat out while bonding with colleagues/networking.
Avoid running a car if at all possible- really expensive. Get a bike
Don't smoke or take cocaine or take up gambling.
Don't compare yourselves to others in terms of what they can afford -they may have family money they aren't saying anything about, or be running up massive credit card debts, or be stealing money from their employer. You never know the full story.
All schemes that promise rapid riches from just a few simple steps are A SCAM.
Store cards, hire purchase schemes, buy now pay later schemes like Klarna are all terrible ideas. If you can't afford it now, don't buy it.
That said, having a credit card and spending small amounts that you pay off every month is a good idea to build up your credit history
