It's Monday, for one thing. That means that if you are in need of a fresh start, here you go! It's here. Use it! Let it be the starting line for you becoming the happiest you have ever been.
Know what else is here? Summer. (Or, if you live up north, maybe it's alllllmost here for you). And there's something about summer that just seems a little more light and carefree, even when you become an adult and summers are really no different than any other time (lame). There's something about sunshine and barbecues and pool days and vacation that just whispers, you should really, really be happy.
So whatever it is you need to do today in order to be happy, I think you should do it. If you need to quit a bad job or a bad relationship, do it. If you need to get healthier, do it. If you need to make amends with people in your life, do it. If you need to get back to that hobby that makes your heart sing, do it.
Wherever you are, whatever kind of mood you're in, whatever circumstances you find yourself in, I just wanted to remind you that life is both entirely too short and entirely too long to not be happy.
