Well, nothing is easier then adding constraints. Removing them is what's difficult - so why don't you add them back if it makes you a better programmer and you enjoy doing it more?
Personally, I think the reason you enjoyed it more as a teenager is just down to the fact you were fully in control of what to do and had no external pressure to earn money etc, so if anything you had less constraints - at least from my point of view
