to do everything one can
💪🔥 FEN sounds like FAN the flames + LI like LEAP — fan your effort into a leap
大 (big) sits atop 田 (field) in 奋: a big push across the field. Add 力 (力 = strength/power) and you get striving with every ounce of force you have.
力 — pictograph of a plow or arm muscle
力 originated as a pictograph of an ancient plow, the main tool requiring physical exertion in early agriculture. Some scholars also see it as a flexed arm showing muscle. From this concrete image it broadened to mean 'strength, power, force, effort'.
