The best parts about turning 40

Before we get into all of our 40th birthday wishes, we thought we’d quickly touch on the importance of this milestone birthday. First of all, forty is a great age as you’re not super young nor are you too old. Most importantly, this means you can still go out and enjoy yourself and be silly but have had four whole decades to learn about yourself too.

At this point, you’re not going to put up with things that don’t fit into your life and won’t feel guilty turning down a night out in favour of a chilled night at home. You’ll likely have figured out what you want from life and feel more self-assured than ever before. Doesn’t this all just sound great? Now we know some of the best parts about turning 40, let’s delve into all our different ideas for 40th birthday messages.
