You may be second-guessing yourself a bit too much on Monday, so try to silence the internal chatter. Follow your instincts. You will be feeling strong and creative midweek, and you might feel the impulse to extend your trip in some way.
Try something outlandish this weekend, even if your travel buddies shy away from it, and even if you think you can't really afford it. You might meet someone on Sunday that resonates with you on a deep level.
