What was the last thing you learned how to do?

The last thing I learned how to do is to let go. There's been a lot of stress in my family life lately, and I have had to learn to accept that I can't control other people's decisions.  I can offer advice, and be there for them, but I have to focus on living the best life I can.  I cannot let their choices affect my life to the extent they have.  And while it's been a hard lesson, and I'm still learning how to do this better, it has lowered my blood pressure!
