Yes, design can make you happy.

I didnt think that personal style had much value in graphic design.

I myself am doing a full year of experiments every seven years, but I'm sure many other divisions are possible, depending on the field, the possibilities, and personal preferences. One hour a day or a day a week.

You're authentic when you're honest.

Hobbies are for people that don't like what they're doing.

The question I wanted to answer was, could I train my mind to be happy the same way one trains ones body?

If you want to communicate something, youd better make sure that your design piece is well-dressed and that its teeth are fixed. At the same time, I still believe that if it is only stylistically great and it has nothing to say, it still is not going to make a lasting impression on anybody.
