Every one of us should have this attitude to life: if you give your work meaning, you will feel happy regardless of the amount of the work, and the level of the self-set grades will make people enjoy the work  If you don't like doing it, any simple things will become difficult and boring  When you yell that the work is tiring, even if you don't work hard, you will feel exhausted, and vice versa
If you see work as a pleasure, life is Heaven; if you see work as a burden, life is hell
Finding fun at work makes life better.
