I have had hard time identifying non-materialistic ambitions. My mind has always been able to short circuit the ideas, similar to the ones you mentioned, as a way to make more money. Effectively turning them into greed, which is supposed to be bad. But I think I have been making wrong conclusions. As mentioned in other comments, developing a stronger feeling towards non-self pain points and retraining my mind would probably be the way to go.
Most of my beliefs are for self. Mostly because of the idea that each of us is a random instance, executing for optimizing random functions. Some are aware of the functions, and for some it is a black box. This breaks the boundaries between right and wrong etc in my mind and so on. But also diminishes the idea of exposing these beliefs and doing something with them seems meaningless.
Don't let yourself confined by what's "supposed to be". Trust your emotional state derive from what's good or bad from first principles (i.e. from experience).
That said - it's good to do an exercise and imagine it's 10 years later, you've created a company startup for the sole purpose of making one billion dollars, think about what you can do with the one billion dollars, what opportunities you've sacrificed, what you've risked.
How do you feel about it? Was it worth it? Would you do it again?
The answer might be different for everyone.
You can repeat for any other number of ambitious goals - getting married to a very good person; spending two decades raising children; moving to a new country; or even getting divorced; travelling around the world; becoming the best at an activity; become world famous for something, etc.
For any one goal - think, what kind of person tend to achieve that goal easily, then the price of achieving that goal is to become that kind of person. Do you still want to achieve goal? If I didn't want to become the kind of person who'd marry my partner, it means to me I didn't actually want to marry her to begin with. Personally, to achieve X, is equivalent to, to become the person who achieves X easily.
I have come across a lot of folks in my life who have comfortable lives, by virtue of working hard for it or being born into it, and too have observed that they fall into a slump, such that a major shift to that lifestyle can bring them down to their knees. I am, frankly, scared of landing in a similar situation. I do try to keep myself sharp by reading/trying out things here and there, but since I don't apply them to a meaningful extent, I have hard time trusting these.
As far as sharing the stuff I know is concerned, I have held an opinion that I don't have any new knowledge. Most of what I know has been derived from works of others, and all of that is already available out there. So I have felt that duplicating that information just increases entropy without any meaningful gain to anyone. That is why I haven't made an effort in that direction.
I might sound like a bad human saying this, but I think I have been largely apathetic about the world. I do think about the worldly issues, usually going into a zone such that I am unable to sleep at night, but I don't think I have ever taken a step to contribute to it meaningfully. I will take up your suggestion and see if I can start putting my skills to use in that direction.
