I am both a SharePoint developer and consultant @teamneusta with over 15 years of experience with creating collaboration and modern workspace solutions using Microsoft tools. My favorite quote is "When all you have is a Hammer, everything looks like a Nail"(Abraham Maslow) Why? Because our world is complex. And a single tool or a narrow perspective won't help with complex problems. So, i think that lifelong learning, trying new technologies and talking about them to others are extremely important things.
