“Give me six hours to chop down a tree and I will spend the first four sharpening the axe.” — Abraham Lincoln
Great tools are a force multiplier and worth investing in. (Invest in force multipliers) An axe is a great example: you can be the strongest lumberjack on the planet, but if you have a dull axe a weaker lumberjack will still cut down trees more quickly than you.
Caveat: even the best tools are useless when used improperly, and Avoid shaving yaks.
“Always choose the best tools that you can obtain and afford. Quality tools give you maximum output with a minimum of input. By investing in force multipliers, you free up your time, energy, and attention to focus on building your business instead of simply operating it." — The Personal MBA (source)
