There will be times when you succeed and times when you will fail.
So, wasting your time doubting whether you are going to succeed or not is pointless.
Just put one foot in front of the other.
Control what you can control.
And then you see what the outcome is.
If you win, great. You are going to have to wake up the next day and do the journey over again. If you lose, sucks. But you have to wake up the next day and do the journey over again.
