Feeling of defeat

Some days I feel defeated.  My mind is so singular that I get on one project and won't stop until I succeed or fail.  Today I am feeling defeated by my current project.  It's interesting though because I take a step back and it's really not an issue at all.  It's a minor setback but my mind tells me it's earth shattering because I can't figure out how to fix it.  Truthfully it doesn't really matter. I will fix it or replace it, it's not a big deal and I am coming to terms with that.  It's important to come to terms with what you consider to be defeats and figure out how to resolve them.  Sometimes we have to concede failure other times we have to make a new plan for success.  As Thomas Edison once said "I have not failed 10,000 times. I have successfully found 10,000 ways that will not work".
