There are no limits other than the limits you place on yourself.
The most successful people place great importance on personal development. They look at personal development as a way to build skills and qualities to improve their lives and prospects for the future. Even when they reach the pinnacle of their career, business, or other achievements, they still make time to continue to push themselves.
When we commit ourselves to become lifelong learners, even when we get to the top of our field, we naturally attract greater levels of success. I once heard someone say that a book is the only way you can get in front of an expert and soak up their wisdom for less than a $20 investment. So true.
Dont worry, I went ahead and linked some of my favorite book recommendations and included a few that were suggested to me that are on my list to read. Most of these books are also available on audible, should you prefer to listen to books and absorb the information in that way.
