Two concept from stoicism that would be great to incorporate into stoicism are:
1. Memento Mori, which is generally denoted by a skull - a literal and inescapable reminder that "you could leave life right now"
2. Amor Fati , which is generally denoted by a flame, is a mindset that you take on for making the best out of anything that happens
What I am envisioning, based on images above, would be taking the text styling of the first image (top left corner) for Finance $toic on either side of an image of a Flame (the Amor Fati), which as it flames conveys the image of a skull (Memento Mori), in a fashion like the Hart and Buck - i.e. if you look from one direction you see flame and from another, skull perhaps.
It would be great if the image and text could be a gold leaf on a slate gray or burgundy background, like this Seneca piece for Tim Ferriss: https://tim.blog/2016/01/22/the-tao-of-seneca/
The $ in Stoic would ideally not have the line go all the way from top to bottom, but rather be just over the top and the bottom of the S to convey a $ sign without being too literal.
