As a long-time "creator" with hopes of working on tech projects so that one day they may be used in every nook and cranny of the world, I suffered many setbacks. For one, I'm not a gifted individual, and so it becomes crucial for me to try my utmost to make up for that. I achieve equilibrium by committing more than my peers, and perhaps the only person who comes close to my commitment is my brother. I also entrench myself in whatever task I take on, and I do it wholeheartedly, every time... but sometimes, these aren't enough.
Startups, especially one in tech, require more than just knowledge and commitment. They require partners/employees, capital, and most importantly, a valid solution to a valid problem. These requirements are high, and even after one gains access to them, the chance of failure remains remarkably high, as evident by statistics around startup failures.
But, Finance requires almost nothing but capital and perhaps a bit of commitment. Most of what it actually requires is intangible, like patience and sticking to principles like glue, whatever the word for the latter is.
