About six years ago I made the decision to leave my "safe" corporate job and pursue my dream of becoming an entrepreneur. I was scared, this was just after the financial crisis and the economy was slowly starting to recover. Plus my father was dying, it was an emotionally challenging time for me, but I knew that this was my window, this was my chance, I felt it deep within me.
If you're in a slump, where it's career or elsewhere -- give yourself a break, it's really, really hard to unslump yourself. This is why you need a plan and a person (or 3) to help you. Even if you're smart, successful, organised etc... people generally aren't very good at taking advice from themselves.
