Seneca, Epictetus, Marcus Aurelius.
These are the original self-help gurus. Think of the themes they taught. Self-reliance, responsibility, faith, perseverance, tolerance. Compare them to the gurus of more modern times.
What do they preach? Self-reliance, responsibility, faith, perseverance, tolerance. A myriad of other qualities are coached and encouraged, but the point is that they are timeless. You don’t need The Bible to know you should “love they neighbor”. You don’t need Tony Robbins to let you in on the little known secret that personal growth comes by first taking personal responsibility.
“Normal is getting dressed in clothes that you buy for work and driving through traffic in a car that you are still paying for – in order to get to the job you need to pay for the clothes and the car, and the house you leave vacant all day so you can afford to live in it.”– Ellen Goodman
