I don’t think there is anyone who hasn’t asked “why” or “why me” while wallowing in the aftermath of what we view as disappointment or even tragedy. It isn’t as though what happened wasn’t significant, it’s that it over. And while it may very well have been a tragedy, it’s yours now and it is up to you to move forward. The only one who can arise from the why is you.
Take ownership of your life and forget about how or why it happened. You can spend the next year asking why or do something about it. And tomorrow will become yesterday if you don’t act. There is no other choice.
Work on what you can control. Work on yourself. Make your life better. Spend time creating something of value. It’s more about who you have become after the why. Tomorrow should be a reflection of who you truly are.
