Depends on why one wants to left alone?
Example: I am working on a few projects with goals to have completed soon and don’t need chatty neighbors calling or turning up anytime.
I have explained to the social group what I am trying to accomplish and now they understand that I am not snubbing them, but rather have more important things to do.
Other times I am thinking on things from my past and present to better understand what happened and the why?
I like to delve into human behaviors and this is how I meditate on the issues and sometimes come up with a good idea as to the reasons that some people act the way that they do.
There are times that people should actually take time for themselves to determine there next goals, understand an issue, troubleshoot etc
No problem isolating oneself temporarily, but it can get unhealthy if prolonged.
So set a time limit say for example :
I will get out once a week, by going out for a meal instead of staying in .
I will go out to the library and look up subjects that I never read before.
I will if so inclined take photographs around my City/Town.
I will go out every morning or evening just for a breath of fresh air .
If I am bored, it means that you need to find another new engaging interest.
Take up a temporary short term Course.(example: NaNoWriMo writing competition starts
Nov 1,2019 in all libraries ( internationally as well).
Fall is usually when all the Summer activity ends and many are returning from vacations, going to work,school and some get depressed around this time.
At least there is some respite as the Tourists have all returned to whence they came.
Now I can enjoy the walk downtown with out tourists taking up most of the sidewalk.
Living isolated is not safe when an emergency requires immediate help. So living on ones own has its cons as well.
“No man is an island” comes to mind here.
