Straight talk....

I have lived this process. It all starts upstairs. Trust me. If you don't change your thoughts your actions will never evolve. Once you fix your head...you will KILL your goal!! 

Same line of thought....Fix it!!! Stop making every little misstep into a mountain of failures. Everyone makes a wrong choice every now and again....MOVE ON!! You are worth it!!
And stop saying you CAN'T. You absolutely CAN. Perhaps you just chose not too. <3
