Fall: Is it the true New Year? Essay start help.

Hey guys, this is my first time here and I'm not sure how this works. So, I'm trying to write a personal essay about how fall is the new year. I can't get out a good thesis and 3 supporting points to argue for fall being the new year. I'm in Grade 11. Can you guys please help me out? Any help will be appreciated and feel free to ask me questions. :)

Here is something that came off of the top of my head, I hope this helps :) If you write anything, please post it on here and I will try to help with editing it.

Many people feel that the end of summer is indeed, the end of the year. A new year begins every fall, instead of on Jan.1

Reasons:
1) When the weather begins to cool, it is the change of the season, the end of the summertime, for some people the best time of the year is summer, so they feel like the year is over.

2) A new season for shopping, and people begin to think of the upcoming holidays like Halloween, thanksgiving and Christmas.
3) Back to school time and a new schoolyear will definitely make a person feel like it is the beginning of a new year.

Try looking across different cultures, I know India celebrates their New Year around the time that fall happens. Just information o maybe support a point.

Help with mine?!
