Is it really a choice between two equally good things ?
I will say it this way - a five year old could make the choice without any problems at all. Hmm, go to work every day, or sail on a boat everyday ? Wow that is a really hard choice isn't it.
I understand the pull in both directions, truly, but I wonder if it is really a pull in two directions because of the actual desire to be in both places at the same time. Put it another way, if you had all the money you could reasonably want, would the choice still be hard to make, would you still be wishing you were sitting there at home and going to work everyday because its so much fun ?
Maybe the real choice isn't between two really great things, but rather on the one hand a life that has a lot of security, predictability, creature comfort, etc, and on the other hand a life that is filled with fun and excitement, but doesn't have all the other things. If so then I don't really think the decision is between two really great things as much as it is a decision about whether the one really great thing is worth the risk.
