From James Clear:
If you only do the work when it’s convenient or exciting then you’ll never be consistent enough to achieve results.
Professionals stick to the schedule, amatures let life get in the way.
Professionals know what is important to them and work toward it with purpose, amatures get pulled off course by the urgencies of life.
Professionals take action even when the motivation does not feel right
The only way to become excellent is to become endlessly fascinated by doing the same thing over and over. You have to fall in love with boredom.
The greatest threat to success is not failure, but boredom.
