It can be a source of huge frustration.
Especially when it feels as if we're locked in, for example by responsibilities to those we love.
I felt that way about my university course, and to a large extent I still feel that way. But I realize that I can't shirk my responsibilities to chase after dreams, no matter how important they are.
So that means that I have to do both. And that I sacrifice other things, like watching t.v. in order to make more time for things that mean a lot to me.
Of course, I am foreseeing a crunch-time on the horizon when my work and dream-work have to coincide, but until then, I'm investing time in both, trusting that my dedication will pay off.
Are you also frustrated because what you're doing isn't helping you to your dream? Or are you lucky enough to be passionate about what you do?
