Student "Master, how long does it take to become a master?"
Master "If you train hard it will take 10 years."
Student "Master, I am willing to train twice as hard, how long then?"
Master "In that case it will take 20 years."
Personally, I don't think there is anyway to make up for "lost" time. Always train as hard as you can and be true to the martial way and tradition. I find my greatest achievements (martial or not) often come when I just let them come.
Okay, technically I suppose if you quit your job and train in martial arts as a profession you could make up "lost" time relative to other people who keep working and train with less frequently, but even the I wonder whether you would be internally sabotaged because of the intent??? I can't answer that.
Anyway, if you are putting in 100% to your martial studies you can't put 110% (100% by definition is all you got) ... either you are doing everything you can along the journey or you aren't. If you aren't what are you waiting for?
(joke, Shihan Salter used to say this to us all the time ... doing pushups, you slow down he say "Jason, wait you waiting for?" ... anyway, sorry for the tangent). If you are then just let it all come.
Another stray thought... it sounds to me like you might be concerned that you could be doing more. If that is the case, and only you know, that requires you to look for areas where you could increase your level of training. I don't know if this applies to you but I find there are not enough martial artists who read about martial arts (people are too fixed on the in-dojo training). Maybe that is something you could pursue if you aren't already?
