"How to change a person's behaviour for the better like learning, working, playing or living?" I thought coding smart contracts could be fun as I wanted to learn it. And then I found out that the faster the learning process, the quicker one could get bored with the repetitive steps.
Doing routine work cannot be fun. So I would try to make a difference by taking on challenges, improving continuously and living by my own strength such as building my websites, filling them with my creative texts, photos and music videos. I find fun in every small step and addition.
Playing the same level of a game cannot be fun. I believe instinctively we want twists and turns to change our emotions and grow ourselves intellectually. Whenever and wherever appropriate, I would bring my guitar and sing a few of my songs to engage and stimulate others in a refreshing way.
Excitement and delight can come from many sources and every little fun we experiment or capture can create a lot of fun. The fun we made is the result of our creative minds, and a theory of it would only consume its intensity. We know we can have fun alone, with family and friends, and in life!
