Success is the state of achieving the goal of optimization within whatever subject matter the success relates to.
The solution then to how to be successful at the core is that for you to be able to succeed, you must optimize that portion of your life.
The trick to it though is that is simpler said than done. Reason being that for something to be simple, you must fully understand it and be able to use it with ease which means not running into road blocks. It is not easy to walk up a lot of stairs but it is easy sliding down a slide.
How do we solve the simpler said than done problem to achieve success? We must first know how. A person only is able to know how if they are directly taught or self taught. Being self taught can take you an entire lifetime while someone that is taught may gain the information rapidly and utilize it throughout life.
If you are self taught you need the resources to do so which would be time and opportunity. If you are taught by someone then you need the resources to acquire their training and have the time to do so.
The opportunity to learn how to achieve success is difficult to acquire.
A parents best gift to their children is the gift of all the information they know that can aid them. A free gift of knowledge is a powerful gift to give.
