I was just let go from my job two days ago. Awesome.

30. Actually I was fired twice from jobs in my lifetime.

At the age of 16, I worked on the back of a garbage truck manual handling rubbish.
At 17, drove taxis.

Both temporary holiday jobs, so no great loss.

Worked the next job for 40 years. At times I hoped something would trigger me being free from it. From about 50 onwards, I think.
Never worked up the courage to walk away, not until ill health at 63 decided for me.

Never felt freer in my life.

Sometimes things happen for a reason, one door closes, another opens, etc.

51 isn't too young to declare yourself officially retired, if finances allow.

If not, good luck on the job hunting.
You have skills and experience on your side.
