I feel I've been staying in a lot of the time, and with work form home, my days are blurred. I don't really have reasons to go anywhere. For those of you that have a place to go when you want to go out, where do you go?
You need to give yourself a reason. Even if it’s something small but “frivolous.” When I had time on my hands but was unmotivated to leave my room due to depression I bought a cute bike and that got me out of the apartment. Would bike around Brooklyn and go to Prospect Park. In the winter I would find a cute bar in Brooklyn and grab a cocktail by myself or maybe make an effort to leave the house to buy one nice thing for myself- a book or a coffee mug, something small as I didn’t have much money at the time. I didn’t really have it in me to go to social activities although obviously that would be the best route; a league or fitness classes or a group related to an interest you have. Now I don’t have much time on my hands but it gets depressing to only work sleep and repeat. So walking by the waterfront for 15 minutes or going to a yoga class or even going somewhere other than my usual place for grocery or clothing shopping (I purposely don’t shop online whenever possible) are the little things I’m able to do for myself to get out of the house.
The secret to stumbling is to have a destination, loosely held. You need to pick a direction, so you have enough activation energy to leave the apartment. It doesn't actually matter if you get there, just that you left.
Keep picking directions and you'll make space to wander by a random dance party or art exhibition or amorphous blob of people looking for new friends.
Also, the density of NY makes it easy to chat with strangers. Go grab a coffee or a slice of pizza and you'll probably end up talking with someone.
