You see a quote or Google a concept and get some great info…the you realize the resource is from 2 years ago, or five, or twenty five…
Does that make it a bad, old or tired reference? Maybe. Maybe not.
Good ideas have been around for a long time (and, you probably have some yourself). For sure you can adopt, adapt or customize such concepts others’ ideas to make them work for you.
Consider the content rather than the source. Use your own perspective and situations to decide what might be good for you.
Meanwhile, add to the universe of good ideas and perhaps make someone else’s world better at the same time.
