They say insanity is doing the same thing again and again and expecting a different result.
It's okay to fail, just don't keep failing in exactly the same way.
On the other side of your self-perceived limitations is where the river is flowing. You have to adapt, change, learn, grow.
I can't sleep so I've been sitting here figuring out all the dumb ways I self-sabotage.
Not sleeping is one of them. Calling my self sabotage dumb is another, I am actually extremely sophisticated at self-sabotage! I can make a script problem seem like it was caused by the paper jams and I can convince myself a relationship problem was caused by international terrorism.
But it's when you see your same patterns repeating that you know you have to change.
It's like that moment in a movie when the main character has to decide whether to grow and save the world/get the girl, or to just curl up at home.
In life, even after you change and grow, you can still lose.
But if you don't at least make the leap, you might as well just throw in the towel.
