You're doing the best you can.
Your best today will be better tomorrow. But for now, don't beat yourself up over mistakes and slip-ups.
No one is perfect. You won't always execute your plan exactly. A bad moment or day may throw you off.
But don't let that make you believe you're not on the right track. Don't give up.
Take a breath, get some rest, then just keep doing your best.
I hope you believe in you as much as I do.
