Trouble is I'm not sure this is someting I can do myself.
If there is anything that our human culture on this planet Earth is not short of its cliches. Some designed to encourage someone in a time of doubt.
Sometimes one must get outside of the problem in order to "see" it from a different perspective and by doing so the solution sometimes reveals itself. Its finding the right perspective. That can be different from person to person, day to day. The duties I perform at work include troubleshooting industrial motor control circuits and a lot of the time I am coming in after several people have added and or deleted control devices and circuitry. It can be a real "rats nest" at times and most of the time I have to perform while the plant is in production. I have been told "focus on the tree not the forest."
Fortune favors the bold.
Necessity is the father of invention.
Nothing ventured nothing gained.
"Security is mostly a superstition. It does not exist in nature, nor do the children of men as a whole experience it. Avoiding danger is no safer in the long run than outright exposure. Life is either a daring adventure, or nothing." - Helen Keller
Ok so that last on is not a cliche be it applies all the same. Then there is my favorite - "Proceed with CAUTION" - which is really an encouragement when you think about. Otherwise it would say "KEEP OUT".
