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 it’s easily accessible.
There are lots of books on saving for retirement- I recommend the simple path to wealth because it’s easy to understand, required very few action items, the author crunches the numbers while he’s explaining things, and you don’t have to be someone obsessed with savings and personal finance to benefit from it, like me!
