Grind for the next 10 years; you'll never be stronger than you are now so hit that shit hard while you can. It's hard for young folks to picture not being able to do everything they can do today in 20 years, but that age shit shows and don't give a fuck, so get the grind on now and then pull back and enjoy the ride. Plus you'll find the windows of fun in the grind years - work your plan - stoked for you.
