Combining different skillsets can provide substantial competitive advantages. It is extremely difficult to make it to the top of any specific skill, but way easier to develop a rare skillset. After all, in real life, there often is a need for a combination of a sufficiently high level of skills instead of a single, extremely fine-tuned one.

• Finding a hobby that is not related to your job or study will provide an opportunity to develop the skills that can widen your abilities. To select a suitable hobby, it makes sense to think which skills you would like to develop.
• In the process of building a team, it often makes sense to look for people who can complement each other with their experience and skills.
• If you manage to find a hobby or a study group that takes you in other social circles than your job does, it is more than likely to widen your understanding and social competence.
• Every now and then, it can be useful to pick up a book and study a topic that does not typically belong to your wishlist. That can provide you surprising mental models and a broader perspective on the world.

Developing a variety of skills can provide more opportunities than merely focusing on one area of expertise.
