Get out of there and try new things! Fill your days with activities that are fulfilling and stimulating, rather than time-filling.
Build a library of hobbies you absolutely love doing: both active and passive, indoors and out, solo and in groups.
These hobbies provide both physical exercise and mental stimulation – which have been shown to benefit mood, sleep, brain function, self-esteem, and overall quality of life. Not sure what you like?
Get out of your comfort zone and do something new and scary!
Google the word “hobbies” and see what lights a spark in you.
