Hindsight is of course always 20/20 but you don't have that benefit in the present so don't beat yourself up.
Trust your instincts. Accept falling down may be a possibility and just keep taking the steps necessary to bring you closer to your goal. If you fall, get up.
We are human. We will make mistakes. We will fail. We just need to stop being so hard on ourselves when we do. Accept the good and the bad and know it will all balance out eventually.
And breathe... stop, take 3 breaths, still your mind and open your heart... and get up and carry on knowing you are perfect in your imperfection.
