If you are offended by this statement it is because we do not share the same understanding of the word 'Motivated'. Of course we would also have to agree that your offense is based on your understanding of the word lazy. It is possible for you to 'stay motivated' while also 'staying lazy'.
For Your Consideration...
It has been my experience that 'Motivated' people are less likely to take action, 'Driven' people are most likely to start taking action, and 'Obsessed' people consistently take action. There is no shame in being 'obsessed' with your goals unless your obsession prevents you from thinking clearly, moving strategically, and responding accordingly. Once you understand the difference between motivation, drive, and obsession, you can quickly associate the corresponding behavior related to each. I would argue that anyone at the top of their game has evolved along this intentional journey.
I am often humbled by the question 'Alonzo how do you do it?', while anxious that my response will be misunderstood or misinterpreted. The truth is that I don't know how I do it, I just do it. I became obsessed with a goal and just did it. That's what it means to be 'tacit'. It is not knowledge that can be transferred or explained. You can be so obsessed with a skill or a goal that the constant repetition of action becomes a natural part of who you are. I recommend you commit to your obsession, celebrate the magnificence of what it means to you, and do not stress about the inability to explain how you do it.
I found my 'Magnificent Obsession' and have been Blessed ever since.
