"Above all be of single aim; have a legitimate and useful purpose, and devote yourself unreservedly to it"

This quote by James Allen motivates us to focus on one objective and to devote ourselves to it. It is necessary to have a function that is both genuine and beneficial, as this will help to guarantee that our efforts are not wasted. We need to make every effort to be single-minded in our pursuit of this objective, and to commit ourselves to it without reservation. This suggests that we must be willing to put in the required effort and to make sacrifices in order to attain our objective. It likewise indicates that we need to not be quickly distracted by other pursuits or by the opinions of others. By having a single objective and devoting ourselves to it, we can make sure that our efforts are not squandered and that we can accomplish our goals.
