Answer: The fact that you feel that you are great and smart is good. However, you must keep in mind that you have to be grateful to the Creator for this. Where does all this greatness and knowledge come from? It is from Him. This comes first.
Secondly, what do you really have? What did you receive that you feel proud about? A little child who has received a new toy also finds himself in euphoria, maybe in a state even more fulfilling that yours.
Everything depends on the size of the desire. If it is small, it is easy to fulfill and you will feel like you’re at the peak of success. If the desires are large, it is much harder to satisfy them and you will feel empty. Therefore, everything is measured against your desire, how big it is. For now, our desires are still very small.
Certainly, it is desirable to be in a good state, but at the same time, you must understand that this is because the Creator is shining upon you and not because you have achieved something on your own.
