My grandfather passed away. It inspired me to take more control of my life and to start enjoying things I was afraid of.

I didn't realize I should have been using him as a a role model until he passed away, but when it happened, it was very powerful.

It is also the first death of a relative I've had to deal with in my life.

That is a moment. Thanks for sharing.

Death often has that effect, for sure--it's painful, but can be inspirational at the same time.

Honestly, the same experience verbatim.

While visiting my parents a month ago, they had a scale sitting out in the bathroom. My five year old daughter exclaimed, "Daddy, look how much I weigh! ... How much do you weigh?"

If you had asked me without a scale for reference, I would have said 160 pounds.

It was 172.

172 isn't a crazy weight, but not realizing I'd made it into the 170s (which I'd never been before) while simultaneously believing I was 12 pounds lighter was definitely a "moment".

After a month of very low carb diet, exercise, and other lifestyle changes, I'm down to 153 and feel much better too. :)

19 pounds in a month! That must have been a very low calorie diet, not just substituting other things for carbs.

People are interpreting the question as generally "what's something you wish you started doing sooner", which is similar and more commonly asked. People in the reddit thread did this also.

What you're really after is more like "what is a moment in your life that made you rethink things and change your behavior".

I think they're both valid interpretations of the question. There's a common idiom, "an aha! moment", which can refer to either the source of the revelation or the revelation itself.

Create a topic for your own question.

I don't have a question; I have an interpretation of the OP's question that may or may not be correct. I took "What was your moment" to mean "tell me about the moment" rather than "tell me what you did".
