I believe there are two factors that chip in to make you what you are today. One is the extrinsic part; which is the inputs presented to you by life in the environment that you live in. And second is the intrinsic part; which is how you handle it. As with any profession and the respective work, I believe your design reflects your experiences in life and your outlook towards it.
So, live a richer life. Count your riches with your experiences and not money. Travel, talk to people, experience new lifestyle and culture. Be open towards accepting them the way they are and immerse in their beliefs. Try everything you can get your hands on. A new sport, cuisine, no matter how inappropriate and stupid it may seem. “You have your way, I have my way. As for for the correct, right and only way, it does not exist”. The soon we understand this the easier it will be to accept it. I always wondered what reality is. Though I understood it earlier, but only late did I realize that, “that which is accepted by many is”. Try to see the good in it. To look at it through the eyes of those who firmly believe in the same. After all the more you are open to understanding people, the better you will be able to design for them by empathizing.
You never know how the dots will connect. You just make sure you have enough of them, when the time calls for it.
