When enough is enough

Good morning sunshines! Yesterday was a horrible day... I was hopping to get a call from a job interview I made a couple of weeks ago and instead I saw a new add from the company so I guess I wasn't good enough.

GOD I hate that... Not being enough... I remember reading in one of those sentence-affirmation kind of things: 

"Note to self: RELAX. You are enough. You have enough. You do enough."

And when it might be true there are moments when it's not easy to keep repeating the mantra. Like today. Ok, I have enough, I agree. I do enough, at this point I'm only hoping so... But am I enough?

This kind of question left me eyed open last night so I guess exhaustion just adds up to the pile. My conclusion was... It depends to whom. But my concern here is... I'm the only one judging me, considering I'm not enough, well besides the guys at the job interview because I was perfect for the job, seriously. 

What can I do to avoid that kind of thinking? Is there something I can do?
