For me, finding tiny bits of joy/happiness is easier than trying to achieve it through big things, which invariably are much harder. Finding the perfect partner, job, home etc. Practically impossible.
Enjoying my morning shower with some lovely scented shower gel and a fluffy towel gets my day off to a good start. I practice an attitude of gratitude/gratefulness. How lucky am I to be able to have a piping hot shower, keep myself clean, eat the breakfast I choose and head out to work. I get in my car that 10 years old but is paid for. I like my colleagues, though the work can be dull.
I take a lunch with me that I enjoy, if that's a chocolate muffin and a latte, so what? It made me more happy than a cheese sandwich.
I control what I can and try to be as intentional as possible. I don't drink instant coffee. I don't like it. I won't even drink it to be polite. I'll have a glass of water instead. I do things that make me feel better, not other people. They're all doing as they please anyway.
I eat the food I want to in the evening. Sometimes that's a cooked meal, sometimes cheese and crackers. That makes me happy. I am listening to my body. I don't conform to what society thinks I should be doing to make me happy. I don't like travelling so I don't do it. Been there, done that and realised I just like my home comforts. So what if it's a beautiful day outside. Stand by the window and put your face towards the sun and enjoy the warmth and light for a few minutes. You don't have to be out doing bike rides/picnics in the park.
Start living your life the way you want to, find joy in the small things (a lovely front garden you pass on your way to work, a houseplant, a really comfy pair of slippers or a feel good series on Netflix) it really is liberating and that will bring you a contentment which could help with lifting your overall mood.💐
