Thank you for your response and even as the one who wrote this post, your distinction between significant and best has got me thinking about choices I have made in my 20s that were significant but maybe not the best or most positive.

What are some of the most significant choices you made during your 20s?

My most significant choise was - choosing to travel and focus on career, ahead of relationships and starting a family.

Other people are taking this question as "what are the best choices you made in your 20's". 

But I'm taking it as written, the most significant choices. And delaying relationships/family was a significant choice. 

It's one that I would have made differently could I do it over again.
