Best Advice to Those Starting LATE on the FIRE path??

[FinanceDude]

I couldn't find a topic like this on search, so I am wondering.

IMHO, this appears to be where most people are.........I know some of the folks on this very board were in these shoes.

What would be your best 3-5 points to give them?

Here are mine:

1)Construct and FOLLOW a budget
2)Maximize 401K and IRA contributions
3)Drive the same car(s) for 10 years

I guess this is on my mind due to the circumstance of a friend of mine. Makes over $150K a year, but has less than $80K for retirement, and he's 48.......... :P :P
