In every possible situation, people choose to do nothing because they can’t do what they want to do.
Students don’t practice, because they can’t practice as much as they think they should.
Supporters don’t donate to charity, because they think they should donate more than they can.
To say nothing of the many millions who don’t exercise because they can’t commit they way they want to.
Don’t let your inability to do everything stop you from doing anything.
Just do what you can.
Tomorrow, just do what you can, again.
If you keep doing what you can, day after day, you’ll find that you eventually accomplish an awful whole lot.
