It takes a fair amount of determination to achieve any level of success in life. Of course, you first have to decide what your own definition of "success" really is. For me, it's a strong desire to have a home and land, just enough to plant a small garden, and to afford regular bills and my dream car.
For those just starting out in life, it might be a purpose for the crib bedding they've had their eye on. Or, it could be a yacht on which to sail around the world. Regardless, if you don't keep your dreams off the shelf and fresh in your mind, you may never meet with any success.
It also helps to keep in mind that success isn't the end of the journey of life. It's just a landing place until you stretch yourself to reach out for your next dream.
