Start with something small.
Know exactly what you want.
Ponder its value, all which achieving it will unlock.
See every detail of it. Feel what it will be like to be there, to have won.
Now, relax. Release. Allow it to not happen.
Then, perhaps, your deep inner mastery will come forth and guide you, move you unto victory. Or perhaps it will not. Continue to accept failure with an open heart.
This is doing by not doing.
