This is an abstract from an article wrote by one of my favorite authors, Paul Graham.
Mr. Paul Graham told us two tips about this:
You should have an explicit belief in change. If you consciously remind yourself the world is not static, you start to look for change.
The unfortunate fact is that change is hard to predict. Change that matters usually comes from an unforeseen quarter.The best strategy is simply to be aggressively open-minded.
Instead of trying to point yourself in the right direction, admit you have no idea what the right direction is, and try instead to be super sensitive to the winds of change.
In the real world, we face the opinions from experts. Sometimes, we say something as an expert in our professional domain.
Sometimes, when experts are wrong, it is often because they are experts on an earlier version of the world. They are justified in doing so with opinions about that do not change much.
Thus, we cannot trust their opinions in the same way about things that change, especially the things of Internet.
Can you protect yourself against obsolete beliefs? Mr. Paul Graham wrote: " Most really good start-up ideas look like bad ideas at first, and many of those look specially because some change in the the world just switch them from bad to good."
