I took up working out (some may say religion) aged 17. I was around 125lbs when I started out & 6ft.
I took it up for myself. Vanity, women, etc. were not driving forces for me.
Women come and go, cars and material objects come and go. Your body & your motivation, dedication and lifestyle stay with you to the very end.

I've also been a member of the bodybuilding.com forum & community since 2001. Old school FTW!

If you can look back on your last workout and tell yourself you pushed yourself as far as you could, if you look back on the past year and can say you made some progress, or even helped another person in making progress....
You'll understand.
