Auto deposit part of paycheck into savings account that I absolutely never every touch besides moving that money to betterment (or some other managed investment vehicle). Has never failed me. I haven’t withdrawn from that account in 15 years. Also I get all my groceries from ethnic stores so I save at least 50% there. I also own my house outright so I don’t waste money on mortgage interest.
