Once a year, I literally make a year-long "strategic plan" for my life. A little bit more intense than New Years resolutions. I start with considering about 5-6 broad values - what are the big things in life I most value? I then identify some larger personal goals that will align me and my life more closely with those values, and THEN I narrow things down to the coming year - what goals should I have for THIS year that move the ball forward towards my larger goals, and that align me more with what I truly value. This might be a fulfilling, motivating exercise to engage in on your 30th birthday - sort of starting off the new life chapter with a plan that moves you closer to the person you want to be.
On a lighter note - have you searched
