Our survival instinct's primary purpose is to protect us, so it's always on the lookout for trouble, but that can make us overthink on even the most simple of decisions. It keeps us focused on what is negative and what could go wrong rather than on what is positive and what could go right. This overthinking often causes us to miss out on the happy moments and so we need to learn to override the negative thoughts that cause us to worry about things that may never happen. Luckily, we can stop and ask ourselves, "What is absolutely true about this situation?" Once you start examining the reality of what's happening in the "moment", your thoughts will move away from false fears. Each time you stop to redirect your thoughts and not overthink, you get closer to letting go and enjoying your present time by really being in the "moment".
