Anicca: the doctrine of impermanence in Buddhism. I'm not good at explaining it unfortunately 😂 basically it represents the fact that everything in life is impermanent and transient. It's important to experience life as it comes and goes, as life is in a state of constant flux. If things aren't where you want them to be, don't worry, because the situation you aren't happy with is impermanent. If things are going great then be grateful and really enjoy it and don't cling to it because unfortunately this too is impermanent to some degree. Life is a successive series of separate experiences joining together to give the impression of one continuous experience. But the experiences of yesterday are not the same as the ones of today. Life changes continuously. Basically just live life in the moment, the current experience for what it is. Live without anxiety about the way things are or worry about what will be, don't try to cling to things that won't last. Just experience life as it is, as it comes and goes, let go of the past and don't worry about the future and by accepting the doctrine of impermanence and by freeing yourself from attachment to things that are unstable/uncertain you can find contentment in life.
I get very bad anxiety about life if I'm not where I want to be. My mind lives in the future and I feel like current situations are permanent and I miss out on enjoying the present. Life isn't a journey to a permanent end goal. It's about enjoying experiences as they come and go for what they are. This is a reminder to myself not to worry, enjoy life as it comes, experience life as it is and be more mindful in the moment. And yes, I enjoy the irony that I permanently have the word impermanence tattooed on myself 😁
