I repeat, this is not a drill.
So, why are you living your life as if it is?
Why are you waiting for something to happen before you actually live your life?
What's stopping you from doing what you love now? What's stopping you from being happy now?
Most of all, why are you still not giving it your all?
It's okay to make mistakes. We all make mistakes. But, it's not okay to simply coast through life waiting for something to happen before you do your best and give it your all. You are already at the stage. This is no longer a drill. This is no longer a rehearsal. It never was. You might as well give it your all now.
After all, you won't always have the chance to give it your all. Make the most of this chance.
What are you waiting for?
