Forever

"People who need people are the luckiest people" because they know that if you really want others to be interested in you, you have to show an interest in them.

It's not enough to just be good at what you do, unless you are among that top few who are so famous people fall all over every step you take. (Because they don't really know you.)

That doesn't mean cultivating false friendships, it just means being interested enough to comment and listen and make others aware that you like what they do. Hero worship has a tendency to be short term, but mutual caring can be forever.
