Open a high yield savings account - you get an, obvs, super high interest rate, which is a great incentive to put money in there. Either direct a percentage of your paycheck in there, or transfer money in there immediately after you get paid. Great place to house your emergency fund (3-6 months of expenses) because itโs easily accessible.
There are lots of books on saving for retirement- I recommend the simple path to wealth because itโs easy to understand, required very few action items, the author crunches the numbers while heโs explaining things, and you donโt have to be someone obsessed with savings and personal finance to benefit from it, like me!
