so says a Scientific American article by doing the following things:
- Openness to new experience or learning new things constantly
- Challenging oneself with tougher things:
Efficiency is not your friend when it comes to cognitive growth. In order to keep your brain making new connections and keeping them active, you need to keep moving on to another challenging activity as soon as you reach the point of mastery in the one you are engaging in.
Think creatively and divergently
Do things the hard way – because efficiency is not our friend when increasing our intelligence
Networking – because it is the arena where all the above bullets can be easily exercised. 🙂
