You can also get new gear and then test it riding. It works for me, it could be a new saddle or a new handlebar, GPS, bib/jersey, shifters, fenders or even a new bike. I bought a very expensive rain jacket a few years ago and it made me ride in the rain to test it.
What also worked for me is racing against myself. After work 3 times a week I would leave my driveway and go to the nearest town(6 miles away) turn around and go back as fast as I can, trying to beat my previous best time. Same route, same distance. In two month I saved almost 15 minutes and many pounds.
Also signing up for a challenging epic ride in the future will make you ride more, especially if you do it with friends.
