Whether it be to do your job, get your schoolwork done, clean your house, work on your creative passion, etc.
Bonus points if you’re someone without reasonable self-control so saying something like “I can only have a cookie after I do this/while I do this” doesn’t work for you and you’re just going to eat the cookie and not do it.
I don’t have the motivation to do the whole thing.
That being said, I only need the motivation to start the task. Once started, I don’t need motivation to continue doing the on-going task.
Soo, you may not need as much motivation as you think you need. Just push yourself to start one small bit of the task , and voila , before you know it, the task is over.
