Some things that might help:
1) A clear goal, something that motivates you, something you really *want* to do, not just something you feel like you *ought* to do. For example, your goal could be becoming rich, or reaching financial independence, via
improving your savings rate. Saving money can be exciting when you think of how much better off that saving will make you in future. Saving money really is the #1 first step to becoming rich. It won't get you there by itself, but it is the first step.
2) A method of reducing temptation, such as putting the money into a separate savings account at a different bank that is clearly marked for the purpose.
3) Either reduce your expenses (start with the biggest ones), or increase your income. There are many ideas for how to do this online. If you do either, you'll find it much easier to save. For you, it might be a better shot to increase your income... having crackheads for neighbors does not sound like fun.
Pay off your credit cards first. The amount they charge you in interest is higher than any return you'll get from a savings account, or from most anything else.
If you're looking for a high-yield savings account,
nerdwallet's list of high yield savings accounts is pretty good.
Definitely put it in a savings account. NOT a safe.
Cash in a safe or piggy bank pays you nothing, and it can make you a target for thieves (like potentially your crackhead neighbors).
Cash in a savings account pays you interest, and its much easier to keep track of how much you have (which can feel rewarding, if its growing).
The problem isn't that the money is easy to get. A determined spender will find a way to spend even if they have no money available at all - by using a credit card.
The problem is really that you want to spend more than you want to save for your future.
You need to change your mindset. Take time, on a regular basis, to just imagine all the things that having proper savings will give you.
Flexibility to walk away from a job if you need to. Freedom to do things you couldn't otherwise. Peace of mind in case of unexpected bills / problems. Etc.
Once you build a mindset where you're saving *for* something you truly, truly want, you'll find it much easier to save.
Because you'll realize that *not* saving is really saying no to that thing you really, truly, deeply want.
