The most important of these is automatic savings. Open a savings account, and set up your checking account so that you automatically transfer a set amount each month into your savings account. You don't have to transfer much money _ start with whatever your budget can afford. But making this automatic (and then resisting the urge to spend the money impulsively) will get you on the road to long_term savings.
Lastly, if the numbers still aren’t adding up, you can look at adjusting your fixed expenses. Doing so will be much more difficult and require greater discipline, but on close inspection a "need" may just be a “hard to part with.” Such decisions come with big trade_offs, so make sure you carefully weigh your options. Tip: Small savings can add up to a lot of money, so don’t overlook the little stuff. You might be surprised at how much extra money you accumulate by making one minor adjustment at a time.
