I just finished "Better Call Saul" (no spoilers, I promise).
In the series finale, Saul asked two characters if they had a time machine and could go back in time (or forward), where would they go.
In reality, he was asking if they had any regrets in life where they could get a do-over.
Saul's answers were material in nature whereas his counterparts answered with deep thought and introspection.
I've thought about this a lot since I watched it and to quote the Chairman of the Board, "regrets, I've had a few, but then again, too few to mention."
I won't go into my personal time machine, but I do think it's OK to ponder about these time machine moments, but don't dwell on them. Learn from them. Grow from them. Change from them. But, don't let them define you.
What about you? Whether it be Doc Brown or Doctor Who facilitating, where would you go?
Just remember though...
Saul gone, but not forgotten.
