This is non-negotiable.
You need to have at least one of these two things if you want to get anywhere in life: Self-esteem and a strong will.
Sooner or later, you're going to have to do something hard to reach your goal. If you don't have confidence or a grit, you won't do the hard work that needs to be done.
The good news is that if you have at least one of these qualities, you can use it to build the other one.
The better news is that you can develop both of them, just like building a muscle. In fact, someone wrote about this more than a century ago in a book called An Iron Will. You can download the book for free right here: http://gutenberg.org/ebooks/13160
