I know I've posted about this a million times before, but I really want you to internalize this:
Gaining muscle is a painfully slow process.
it teaches you patience
It teaches you dedication
It teaches you work ethic
It teaches you commitment.
All of these qualities are paramount to be successful in anything else you choose to do.
This is why strength training goes way beyond aesthetics and appearance, it forces you to dig deep down inside, and find that strength to continue doing what you’re doing, and trusting the process, even when your motivation isn’t there.
