Job Seeking, Bird Watching

I saw a group of birds flying atop the trees today. Magnificent site, yet they seemed to be flying in circles. Beautiful structure, great movement, light flying, excellent aerodynamics, but circles. Surely they know what they're doing, I thought, veteran birds like them... and than it occurred to me, they are catching waves, airwaves, you know, those spiral hot air waves can propel them in the direction they need to go. And I, with my un-birdsy mind, trying to row forward, one strait line, great time management, maybe I'm circling a spiral propelling wave now. Maybe there's a great job at the top of all these spirals. I just need to take care and not get too close to the sun, right?
