Don't lock yourself into expensive subscriptions you'll regret not being able to cancel.

Buy everything on discount.

Allow others to give you free stuff.

Have an untouchable emergency fund.

Don't assume honesty from everyone.

Be ready for losing your initial rent deposit, or your things getting stolen.

Don't settle in bad areas just because low rent. You would lose job and commute opportunities and actually spend more money and energy fixing broken stuff and crime rather than concentrating on growth.

Keep your expenditure as low as reasonably possible.

Plan in actual amount of months you can live on pure savings, if it's more than 6 then its good.

Don't underestimate CoL, because if you can be frugal intially and eat bad and stuff, you can't keep going like that forever, and it will drain you, and you will have unexpected expenses (such as dental work that cant be postponed, Mexico is an option when that happens and you dont have insurance)

Have a job or multiple interviews lined up in advance (maybe this doesn't apply to HoReCa). You can always cancel them, but it takes time for an online application to get considered.

Try getting a part-time remote job NOW.

Don't consider the rent price only, but add monthly utilities and actual moving in costs on top of it, like you'd need to buy a blanket and stuff.

Avoid rental or work scams.

Write resumes as per the job description. Don't send same resume for different kinds of jobs. For jobs that don't require degrees, don't even mention it. Make up some jobs and let a friend know that you’re using them as your reference and they can pretend to have been your boss at any one of those jobs. No one even checks anymore, from my experience. Look Good at That job and competent and little else.

People are not reading resumes like you think they are. They don't care anymore. You have to hound employers. You apply to a shop? you walk in and ask about it in person. They'll 'refer you to the website.' "Okay thanks so much I will do that!" Then you go in the next day like, "Hey, I just wanted to say thanks for putting me on the right track for the hiring process. Do you know when the closing period for the applications are so I can keep an eye out? Thanks." etc. etc. etc. Don't be Annoying, but do be squeaky. If you don't know who the employers are, just keep hounding them.

Nepotism works really well right now. If you know Anyone in a field/career, ask them if they know of any openings. If they can talk to HR and refer someone they know. etc.

If you have not stopped into your local state's equivalent of the workforce solutions office, you should have been there yesterday. Getting matched up helps.

Treat getting a job like a full time job. Wake up, put in 10-20 applications based on Every single business along x road that day, then stop by the businesses from yesterday's list and tell each of them thanks for the referral to the hiring process and to ask when to contact again. Then contact every business that told roughly when to call back and ask about when you'll know if decisions were made, and thank them for their time. Structure this around whatever interviews you have, added on top, call and make them tell when they chose another candidate so you can close that communication loop.
