No matter where you find yourself in life, your story is not over. There are still multiples of blank pages still awaiting to be filled; filled with love, heart ache, knowledge, laughter, sadness, anger, trips and spills, what have you. Have you ever thought about what yours will be filled with? What you wish could happen? What you know will happen? Me too. All of the time.
I lose too much sleep overthinking about what could be, what will be, what should be; what happened and why it did...and what I should have done to change how that particular page was written, what would have been better. Overthinking isn't fun, it certainly takes up more of those pages than anything else. Replaying scenario after scenario, just hoping that when you open your eyes that it was just a dream. That page was simply a figment of your imagination. Unfortunately, that's not the case. That page is there forever, but that one page will not determine how your entire story will be.
If only we had a personal magic wand to wave over whatever didn't go right or whatever we suspect will go wrong in the future and correct it...zap. That would be very much helpful and keep the anxious overthinkers' minds at ease. But life isn't written as a fairy tale and your life story isn't a Disney script. Everyone has dreams, but not all will come true. Everyone has goals, but that doesn't mean all will be met. Your story may throw in some insane obstacles---including characters---that seem impossible, that you won't be able to conquer. And that's okay.
Why is it okay? Because your story doesn't end there. You still have many blank pages to work off of; more times to mess up and more times to prevail into success. Don't get your hopes up, but don't give up either. It may seem contradictory, but ponder it for a while, it'll all make sense eventually.
After all, look at your story as a work of art in a painter's sense. When painting, one minor "oopsie" in a painting that was a complete mistake can be observed as one of the two things: 1) it ruins the painting and the artist's vision or 2) the artist embraces the mistake and changes the picture to compliment the blemish to make it look as though it was meant to be there all along. Always go with option 2. That blemish won't be the end of the world, who knows, maybe it's for the better.
When the going gets tough, the tough don't always get going. It's not going to be easy, but it's your story. It is only what you make of it. What are you going to create with your blank pages?
