Help with saving!

I’ve always wanted to be one of those people who bargain hunted and protected their money. However, I always find myself spending a lot and can never find the motivation to save. I have $40,000 student debt and still continue to spend. My faults are that I always think quality over quantity so I always buy the best version of what is out there (I.e. always buying name brand clothes, groceries etc.) Any tips or motivation that you use to save? What spending limits do you set for yourself and what is normal spending? I’m in need of a kickstart.
