I have built a “content engine” (more on that in a future post!) that provides a steady stream of learnings, ideas, and connections, all of which amplify the quality of my investing, business building, and content creation pursuits.In this post, I’d like to share some of the most powerful ideas I have come across over the last year, with additional notes and insights where helpful.So let’s dive right in: 20+ high-impact ideas on business, investing, growth, and life…Time BillionaireTime is our most precious asset.When you're young, you are a "time billionaire”—rich with time.

I would encourage you to think deeply about the same…Darkest Hour FriendsIt's easy to be there for people to celebrate their wins. It takes character to show up for them in their darkest hour.People never forget those who supported them when the chips were down.I call these your “darkest hour friends”—find them, treasure them.Engineered SerendipitySome of what we call "luck" is actually the macro result of thousands of micro actions. Your daily habits can put you in a position where "luck" is more likely to strike.It's possible to increase your serendipity surface area and engineer your own luck.Sahil Note: Serendipity surface area is an interesting concept. When you’re on a “track” in your life or career, you are walking on such a narrow path that very little luck can hit you. The more you open yourself up to the world—to new experiences and people—the more you expand your serendipity surface area. There’s quite literally more area for luck to strike.Leverage"Give me a place to stand and a lever long enough and I shall move the world." - ArchimedesLeverage is anything that multiplies the force of your inputs.Building systems that provide leverage on your time, money, and energy will allow you to create a life you deserve.Sahil Note: Leverage can cut both ways. When used too aggressively, it can be a negative (just ask Archegos or the founders at Long-Term Capital Management). Beware of over-leveraging your life or pur
