1) It's not easy to decide
2) It's not easy once you make the leap
3) It can be scary
And most importantly,
4) It's no worse than what you are currently experiencing. In fact, it's 100 times better.
All the fears and challenges and difficulties you imagine are waiting for you - well, yes, they probably are. But if you look honestly at what you're currently doing, there are fears and challenges and difficulties there, too. It's just that you know what they are, and perhaps, if you're lucky, you feel like you have a handle on most of them.
Same is true once you take the leap. You'll adjust. You'll see the challenges. You'll rise to them.
And it will be way more fun and satisfying.
Do what you love. It's the only thing that will save you. Time is short. Life is short. Don't wait another minute to bring meaning into your life with all the energy you can muster.
If not now, then when? If not you, then who?
Love to you all!
