Most people focus on trying to fit more things into their day. The people I see who are massively successful are very good at choosing what things they don't do. Just like you have to remove items from your budget that aren't providing value, you must remove items from your schedule and commitments. Winnowing your commitments in this way creates the space you need to learn, grow and try new things. Most of those new things will turn out not to be valuable and you'll drop them, but some may turn out to be immensely valuable. When you see people that appear to be very lucky, often they have a way of increasing their chances of discovering things they find valuable. Intentionally stopping things that fall below a certain threshold of value/importance is a great way to give yourself room to discover things that are above the threshold.
