Sacrificing vs. Settling

[Mark Douglas]

When you're aiming for a goal (freedom number, for instance), how do you balance the sacrifice of immediate comfort with not going "overboard"?

Example: Saving for a down payment, or waiting to buy another property till I've got sufficient cash reserves in the first property.

I'm fairly disciplined, but I feel like I'm running my goals through my mind nonstop, all day, to try and stay focused. It gets burdensome after a bit, like this is all I'm focused on (which it is). At what point can I let up?  Should I try to grow at a slower pace?  

For context, I bought my first property in March '16.
