You will have more energy.
Somedays you won’t feel like doing the work.
Here’s a tip, don’t just think what you’ll gain by doing the hardest/necessary work but what you’ll lose.
Do you really want to be in this same position in a year or two or five or ten? Do you want to drift for the rest of your life?
Remind yourself of who you want to be.
The person that gets the work done?
Or the loser?
Your choice.
