burnthesheep has good advice. Get involved in the community and growing the sport.
Do you have a distinct off season phase with a few months of de-training and lower TSS? I am usually quite excited to FTP test and start putting in miles over the winter. Subsequent FTP tests with higher values are equally motivating, and then I'm racing. I'm usually pretty done and tired by the time summer roles around, and I make a point of not training big every weekend and not racing for several months.
Real periodization is probably not needed for an amateur like me that tops out in the 90-100 TSS range, but I feel like it is rejuvenating mentally.
