Some people specialize in a specific field, others are generalists. The thing to remember is that whichever group you fall within, there are experts who can help in various ways.
Even if you are the worlds leading expert in a certain field, there are other areas of life where you can use help.
The only person who doesn’t need help from other experts is the person who thinks they know everything and those are actually the people who need the most help.
Have a great day!
