What you are missing out on now to get better is not a sacrifice.
It's an investment.
It's an investment that will give a bigger return than any investment you will ever make over the course of your life.
Building the life you want will require the overwhelming majority of your time, effort, and energy.
This will leave you with next to no time to participate in all the "fun" shit.
While this may seem like a sacrifice...
It only will be if you choose to see it as one.
The reality is...
You're simply choosing to invest your time, effort, and energy in your future.
Don't let people talk you out of what you really want for what you may enjoy right now.
Short-term gratification is the chain that will keep you bound to a life of mediocrity.
Start investing in the actions required to build a life of greatness.
It's a decision you'll never regret.
