Life is too short to fear rejection. The future isn't promised, so worrying about it won't do you any good. There's nothing like the feeling of being courageous enough to go after what you want. It's a rewarding feeling to at least try something even if the situation doesn't play out as you expected.
Being around a lot of people we feel forced to spend time with, doing an insane amount of driving trying to prepare for festivities and holiday parties, looking back at what didn't happen this year and trying to finish off anything remaining on this year's to-do list can bring up a lot of funky feelings.
