Is this a good idea for a blog?

Yeah its wise that you write about your passion or problems. But that doesn't mean that people want to hear about your problems and failures. I am sure that you are writing these so that you can point your audience to right direction. The bad decisions you made so shall not be repeated.

But people mind doesn't work on the philosophy. What can work is if you write how you overcome all those problems and failures. No matter what happened how you succeeded in high adversity. People love to hear about these inspirational things.
