Is 4% SWR too high for retiring early?

[FUEGO]

I'm planning on FIREing sometime in my 30's. Rough number I'm planning on is somewhere around 3%, maybe a little higher. Not 4% I don't think - too great a risk of exhausting assets.

Part of my rationale is that my dividend yield on the current portfolio is just shy of 3% and I'm not even in any dividend focused investments. Hard to see living on one's dividend stream from a diversified portfolio as that risky as long as you have a little cushion in your budget if the dividends go down some.
