When I graduated high school, one friend left me these words:
"Don't miss temptations".
Another said:
"The only things we regret in life are the chances we didn't take".
Luckily, I listened to both of them and have no big regrets.
I do wish I would have gone off backpacking across Europe the summer after I graduated from college (I always said I wanted to).
Of course, I would probably still be paying off the trip if I had gone.
But seriously, why regret the very things that have shaped you into who you are today?
