You can do better. You can be better. Always. If you don’t think so you are only fooling yourself. You must invest in yourself.
If you put your money in a can and bury it in your backyard, it will earn nothing. If you invest these funds instead, they will have the chance to grow. The corollary is if you do not take the time to improve yourself, to learn, you will become stagnant and, in this fast-paced world, probably be passed by others. If you instead work to improve you will grow.
This also should involve improving in your given business or in your personal life. It can be class related to what you do or guitar lessons or for me, keep up with current legal opinions.
I know you are busy. I know you don’t think you have time. But the truth is you don’t have time not to invest in yourself. If nothing changes, well, you get thee idea.
So think about what you can do by investing in yourself. It not only can make you a better professional or person, it will help improve the world around you, your world.
