My thoughts on how to expand your mind (in a good way)
1. Find really clever people, read their material, listen to their talks. Learn to think like they do.
2. Study outside the box. The best breakthroughs come from cross-disciplinary sharing. Learn in one area and apply in another.
2. Stay on the cutting edge.
