In order to know what you want in life, what you're interested in, what your passions are, you have to spend time with yourself. If you're constantly surrounding yourself with people, you can't understand who you are. You put your energy into pleasing other people, but when you're alone, that energy is focused on yourself.
i see solitude as metamorphosis. you need that time in the cocoon to really check in with yourself and the joy of that comes from how you'll gain a deeper understanding of yourself. sometimes i spend SO much time with myself that i get SO BORED that I HAVE to venture outside of myself. when i say venture, i mean challenging myself in how i self- express which will in turn, nourish my interactions with others when i choose to seek company. proceeding to create art, but trying new methods. going down youtube rabbit holes of things i am interested in so i can discover new references. cooking a meal without following a recipe and surprising myself. making the space i am in super cosy (candles, snacks on deck, music, blankets) going on long walks and picking up conversations with strangers through shared observations of life around us. watching music festivals/boiler rooms and dancing around my room like a mad man. once you feel comfortable in being by yourself, you'll be more aware of what you need from your company and when you seek it, you'll be a lot more intentional about it and cherish it even more.
basically anything you've been thinking about trying out- DO IT NOW! breakups are always painful but from personal experience, the ones that hurt the least were the times where i had my focus set on what i really wanted to do but maybe didn't before because i was focused on the other person.
I went to a very beautiful place with my cigarettes recently and smoked them all (pic unrelated yet still beautiful). Much cooler than vaping, and better for you some might say.
