Whats the one investing?

We all start somewhere right? For me it was realizing that time in the market beats timing the market. That simple idea totally changed how I thought about long-term investing. Before that I was always trying to predict dips or jumps. Now I just focus on consistent contributions.

Was there a specific concept or piece of advice that just totally reframed how you approached investing? Something that suddenly made it all make sense or less intimidating? I'd love to hear what helped others on their journey.
