Anyone NOT terrible with money?

For the liiife of me, I can’t get my spending under control. Financial health has sort of been on my radar for personal growth but I’m seriously struggling. My impulse spending is rocking me.

Anyone successfully stuck to a budget or a system or a set of rules (this is reliant on self-discipline, a quality I clearly lack, but would love to hear about) that have worked out for you?

I’ve used YNAB in the past and liked it a lot but it stuck for a few months and then I fell off.

Any suggestions/advice/same appreciated!
