Not all genetic combinations are destined for financial success. Some are in fact destined for failure. The same holds true for the environments we are born into—parents, country, time in history, etc.. It is not our job to correct or circumvent these destinies. From the point of view of evolution, our duty in life is to fully express the situations that we are born into, even if it means we can’t survive and have to die early. Evolution itself does not know the future or what’s advantageous for survival; that’s why it creates diversity. It’s not our job to figure out how to survive. Our duty is to express what we are; an amalgam of genes, environments, and timing.
If your natural compulsion is to sing the blues, then keep singing until you can’t, even if it means you would die poor and unknown. The fact that you did not succeed is not your problem or fault. You will have completed your duty in life; that’s all that matters.
