To live our lives trying to avoid mistakes is one of the biggest mistakes we can make.

Most of us use our calendars all wrong: we don’t schedule work; we schedule interruptions. Meetings get scheduled. Phone calls get scheduled. Doctor appointments get scheduled. You know what often doesn’t get scheduled? Real work.

The greatest mistake you can make in life is to be continually fearing you will make one.

If you are late in doing one thing you will be late in doing everything.

The biggest mistake people make in life is not trying to make a living at doing what they most enjoy.

If you don’t plan your time, someone else will help you waste it.

The biggest mistake we could ever make in our lives is to think we work for anybody but ourselves.

The biggest mistake most people make is to not see themselves and others objectively, which leads them to bump into their own and others’ weaknesses again and again. People who do this fail because they are stubbornly stuck in their own heads.

You will never find time for anything. If you want time, you must make it.

Scheduling is spending your future time at a steep discount rate.

The biggest mistake I made is the one that most of us make while doing this. I did not live in the moment enough. This is particularly clear now that the moment is gone, captured only in photographs. There is one picture of the three on them sitting in the grass on a quilt in the shadow of the swing set on a summer day, ages 6, 4, and 1. And I wish I could remember what we ate, and what we talked about, and how they sounded, and how they looked when they slept that night. I wish I had not been in a hurry to get on to the next things: dinner, bath, book, bed. I wish I had treasured the doing a little more and the getting it done a little less.

The most dangerous way to lose time is not to spend it having fun, but to spend it doing fake work. When you spend time having fun, you know you're being self-indulgent. Alarms start to go off fairly quickly. If I woke up one morning and sat down on the sofa and watched TV all day, I'd feel like something was terribly wrong. ... But the same alarms don't go off on the days when I get nothing done, because I'm doing stuff that seems, superficially, like real work.

...the biggest mistake people make is not acknowledging fear and uncertainty.

Whoever runs your schedule is the most important person in your world as Leader. You need time to think, time to study and time to get the things done you came to leadership to do. Lose control of the schedule and you will fail.
