The best advice I've ever heard is listen to it all, and "then" follow your heart/gut, sometimes even against the support systems that support you.
Only you know what you want to do. Most don't ever clarify what they want. Start with the end point and then build to it.
If you're a leader, my experience is you are best being mentored by an entrepreneur in the industry "you" are passionate about. While education at a university or college can be beneficial, some of the most successful business leaders thought for themselves, blazed their own trail, and built a massive, influential enterprise.
Fred Smith was told by a teacher that his idea for FedEx was a poor one. He was given a "C" for his brilliant idea.
I don't have confirmation about this next statement, so don't slam me "Fairfax Underground Style" if I'm "off," but if it's true, it's ballsy... Fred Smith put $5,000 on the black jack table to generate income at some point in his FedEx venture to keep things moving forward. Again, if that's true, it demonstrates that "big vision" entrepreneurs creatively find solutions because they're building a dream which ends up providing a livelihood to many.

My bottom line point remains steadfast... Your best bet for discovering and building perpetual happiness in every area of your life is clearly define what you want and seek the best way for "you" to accomplish what you are passionate about.
All the best in your adventures...
