I've been using a hashtag over the past couple of years - #morefunlessfear. I didn't invent it myself but I can't remember where I originally saw it. What I do know is that I've been trying to apply it to my life ever since.
"More fun, less fear" seems like a pretty good motto for making sure you take the time to try new things, get out of your comfort zone and really live.
#morefunlessfear has encouraged me to take steps towards living more in my life - both baby steps and giant leaps. It's been the final push over the edge of making decisions that have led to interesting experiences that I know I would've regretted not trying. It's made me more of a "I'm glad I did that" person instead of a "I wish I'd done that" person, and I'm grateful for that.
Regret is something that I try to avoid and as I get older, I'm more and more conscious of it. You only get one life, so don't live it on the sidelines. Take the trip, spend the money on that Kate Spade bag (no arguments here, I'll always spend the money on the Kate Spade bag) and rarely turn down an opportunity to try something new. You never know where it will lead you and how it will change your life.
