This is such a cliche topic, but I don't care, I want to write about it anyways. It seems these days that a lot of people do not differentiate between value and money, and this leads to problems.
Other people can create value through other avenues. One person might be a really good artist, another person might be a great teacher, whatever. The most important thing is to create things, whether tangible or intangible, that benefit the lives of other people. If you can figure out what exactly you can do to improve other peoples' lives, the money will chase you instead of the other way around.
This is because money is simply a measure of value on an imperfect "ruler" or "scale". By chasing money you are essentially grasping at the ethereal and abstract versus the worldly and concrete. In chasing money, your thoughts and energy are focused on the measurement of value instead of value itself, which is something that I believe is not very fruitful in the long run.
So to summarize: Focus on creating something that will improve the lives of other people. Whether this is through making artwork, providing entertainment through athletic ability, mathematical acuity, interpersonal skills, or anything really, as long as it improves people's lives, and as long as you can do it consistently, you will not have an issue with money. That is because money follows value. By focusing on creating value, you create a sort of gravity field that will pull money towards you....
I am still a young buck, and I have not accumulated enough wealth so that I can let it speak for itself yet. But hopefully in a couple of years I will be able to read this post and say to myself "you were right!"
