One of the things that I like so much about the people who are into hobby robotics is their fearlessness. There is virtually no fear of failure among the group. They are adventurous and willing to try new things. A failed experiment is just as good as or better that a successful one because it teaches something. They are willing to abandon an old idea when a better one comes along, even if they have much invested in the old one. They are willing to share all of this information with others admitting to both triumph and disaster. When something works, they give the answer away unselfishly. When something bombs, (sometime literally going up in smoke) they continue to work undaunted having learned at least one way that will not work.
Without fear, without selfishness, there is only the love of the work itself and the learning. Failure teaches as much or more than success. Failure seen this way is success, for it moves the process toward the goal along its way.
Many of the folks who share their ideas on web forums have mottos attached to their signatures at each post. Things like – “There's nothing like a new idea and a warm soldering iron,” or “Never give up when things go wrong.” or "The first rule to being successful is 'Learn from your mistakes', The second rule is 'Be willing to make mistakes.'"One of my favorites is – “lets see what this does... KA BOOM (note to self do not cross red and black)”
Fearless! I find great hope in trying to live this way.
