It’s metaphorically speaking the person you invited to a gathering you organized because you felt obligated to but not really wanted in the first place. How many times has that unwanted guest appeared whenever you’ve thought about doing something/whilst doing/after doing? What was meant to be just an experience has turned into this unpleasant vibe because that person happens to have an impact on you that’s quite stinging. You may or may not have been able to come to the conclusion that it is not at all about inviting an annoying person. It’s about doubting yourself which you might have let into whatever situation it once occurred to you or perhaps even are experiencing right now that happened naturally as though it’s what you’re supposed to do. As I see it doubting yourself has quite the negative undertone since it mostly stems from the belief that you are not capable enough. That belief can be based on comparison/past failures/fear of judgement/the need of permission to create. It in fact is our brain trying to protect us from possible risks and thus using it’s survival instinct trying to keep us alive since it isn’t exactly aware of the fact that when the reason we doubt ourselves happen to become true we won’t die from it. At most what will happen in fact is that our ego get’s scratched which will hurt a little yet won’t stay forever. Besides those moments are necessary in order to grow. So then why do we feel this obligation each time we do something to allow the self-doubting thoughts which lead to physical and emotional ‘pain’ when we know it is nothing more but our (in this current society mostly unnecessary) survival instinct? If you can start questioning yourself that instead of letting it control you it will get easier to see self-doubt for what it is- ridiculous. Why listen to it when it serves no other propose than that it’s trying to keep you from all the potential you have out of fear. It might show up like that unwanted guest yet you can ignore that person- who will then notice it’s not really accepted- which will make the decision to maybe not come the next time you invite it. So maybe just not invite it in the first place?
