I think the human being should not be afraid of taking any decision, because every decision closes the door to 10 other options that could have been made, but will not come true, because you have chosen a way you think is best. And if you once decide wrong, well, that is in the past now, and all feelings, including regret, is taking place in your hear. trust in yourself, because fear is a powerful force we should not let into our brains and thoughts. I always trust my gut, because it is the safest an most honest way to decide :)
