Check out what Joseph Cambell says in his DVDs and his books...it boils down to "follow your bliss"...which means do the thing that inspires you....
...while you are working on that...try to do what Eckart Tolle says to do...and learn to accept not knowing for a while...if you can accept uncertainy...you are learning to TRUST the universe and LET GO of your desire to know all the answers...
Get out and DO THINGS that you enjoy doing...if you are not enjoying what you are doing...stop doing it....if you can't think of anything better to do...try
eating right and blogging about it...
Exercise
Helping people in need in new and different ways...
Join a club that interests you
Try to join a meet up group that interests you...
Everyone has a passion...one of the goals of life is to find it...it took me about 40 years...I think I finally found mine!!!
Stay light!!
