Lol! Very funny story about you and your cousin. That's a great testimony, thank you for sharing and in such detail.
Printing out a picture of your "ideal body type" is an excellent motivation tool. It does make you want to pump out a few more crunches or hold that plank for just 10 more seconds.
Your cousin, whether intentional or purely by chance, is an excellent fitness psychologist, lol! I hope that doesn't blow his head up too much for you to have to deal with. Joking aside, accountability works best when It comes from an outside source.
My suggestion to for you, Iburmaster, is to try and consider finding a workout partner or someone who can challenge you. Preferably someone who is more motivated than yourself.
I don't know what your goal is but with your "motivation system" I'm positive you'll achieve it! Good luck next year.
