You made an estimate when you had the least amount of information. Now that you have accumulated more information, the most productive course of action is to revise the estimate and work towards to meet that goal.
1. It's never out of time, for sure. If you want to make a specific change, study the pros/cons and decide whether to do it or not! But you can for sure make the change you want to.
2. Don't fall into the trap of idealizing a life you don't have. The grass is significantly less green than you might think at the other side of the fence.
I don't know this specific case though, and I guess neither do you. If the parent comment wants to come back with some details, I'll reflect on it.
Not gonna blow condescending garbage your way. Your feeling is not unique but not in the majority, and it’s exhausting to hear the ‘have’ ppl with no actual ability to relate jabber on.
Hope you can find bits of joy where you can make them.
