On an abstract level, no decision is wrong or right.
But when you are making major life decisions, esp like the ones in the article like career choices, relationships, which opportunity to take and which to skip, you have a certain idea of what you want. Any decision that takes you further from that objective than bringing you closer to that objective could be consider a “wrong decision” I think.
A different matter altogether that you can always make amends. Regardless, this is what scares people from making those bold decisions, which at this young stage, should not be an major obstacle (again, hit and trial).
Don’t you think?
