When do you give up without being a big, fat, whiny quitter? Ever? After everyone else? Once you are beat to a (maybe just figurative) bloody pulp? Never?
How much can/should you take? What if the miracle would have happened on the next try, except you walk away instead? But what if you keep trying and it never, ever is gonna happen? What if you miss out on the right thing because you are wasting time with the wrong thing?
How about staying with something/one/place because, although it isn’t right, it’s known, which is less scary than the unknown. That can’t possibly make you a better person than giving up, right?
You got to know when to hold ’em, know when to fold ’em. But how do you know?!

That’s life’s great dilemma I suppose; do I settle for what I have or do I risk it (or cast it aside) for the chance at something more. There’s no always right answer of course. Many people live their lives with regret for having not reached for the stars….others are wracked with regret for what they lost in their pursuit of something that now seems rather foolish. I guess if I had any advice, I’d say be happy. If you’re not happy with what you have, change. If you are happy, stay where you’re at. Own your decision and take responsibility for it. It may not be the right one, but its yours and at least you were pursuing happiness. If you keep at it, you might just GET happiness.
Love what Michael Stajduhar wrote! It’s hard to know really. I guess the only good advice is go with your “gut”. Your “instincts.” And hope they are right. 🙂
