No explanation, no apology.

Your life as an actor will have many twists and turns.

Once you have analyzed a question, discussed it and made a decision why explain it or apologize for it. Your decision is made, now just act on it.

The actor says, ‘I should have stayed in town for TV work instead of doing summer theatre’. 

Really?

That has you having regret for the path you took. You decided to do summer theatre and had that experience and now you’ll move on to the next experience. 

You’ll have many different acting jobs in many different mediums.

Try and develop a perspective where you and your work are ongoing. None of your decisions are the be all or end all. 

Being a professional means solidifying and simplifying your work. Explaining and apologizing only creates doubt for you and others.  

It’s misspent energy.

Make your decision and carry on. Have the experience and live your life.
