Rookie mistakes

Let me tell you Alhb, that you being so concerned is a refreshingly good sign that you'll be one of the better Big truck truck drivers out there.
Remember what tinytim and others emphasized ---
You Didn't HIT ANYthing, .... except the dock.
That is important.

Believe me, there will be times when you make the impossible back-in first try and make it look easy. You'll even surprise yourself. Bummers when you look around to see the astonishment on the faces of those who witnessed your achievement, .... only to discover nobody else saw it.

Then, there'll be times when a simple straight-shot back-in with empty slots on both sides,-- Piece-0-Cake. But you'll struggle to stay betwixt the lines for your assigned door, --- and EVERYbody will be watching.
I don't know why it happens that way.

The day will come when you first see a difficult backing situation, --- instead of thinkin' negative vibes you'll be anxious to give 'er a try. Probably git-er-dun, too.

What happened wasn't a "mistake" rookie or otherwise.
It would be a mistake to think it was.
Now, ..... when you do make a blunder, remember, it's a bigger mistake if you don't learn anything from it.

Good luck and best of success.

 

Oh my. The joys and fears of learning all over again possibly why you got out the first time he he he.

Im such a tease... You have to learn by doing. Just be careful, don't break anything or hurt anyone.

 

Couldn't have said it better myself
