2016 has definitely been the best year in my life so far and so much stuff happened throughout the year that I'll always look back so fondly on. Also the year that I "peaked" in.
2010 was also a great year, many amazing memories. 2014 was a good year as well. 2011-2013 were average years.
2015 and 2017-2019 have all been pretty crap years, more negative memories than positive ones unfortunately.
What I'm looking forward to in 2020 is to turn things around and hope that it will be at least a good year for me, after three unpleasant years in a row. I hope this new decade brings a lot to me as well.
