There are many definitions of success. Most of these definitions relate to what you achieve or chase in life. Your limitations can also define success—not only whether you exceed them, but if you meet them. If you know your limitations, and can hit them, you have done your best. Anytime you can do your best, that’s a success. Everything else you get in addition is just gravy. If you don’t recognize your limitations, you won’t know you’re a success and will chase ideals or someone else’s success.
