Yes, I feel often that I am wasting time. But that's only a feeling. What if this is the best I can do now even though I feel the opposite? For example, many people run businesses and are very busy and some of them also succesful. However several years later they realise that it has been only wasting time. After all, one day we will die. In that very last moment it becomes really unimportant what we have done during our lifes.
