The toughest decisions are the ones that provide the most impact in life. Whatever the short term results - temporary pain, humiliation, friction from others; it's not meant to last. What's lasting is the path to your destiny. Every decision, good or bad will lead you to where you need to be.
At the very least, it will teach more bout who you really are, and that's the key to making great decisions - knowing yourself and your truest core values.
