When you find a “truth”, be aware if it's “Your Truth” or “The Truth”. We form “truths” using our own — hence limited — experience, knowledge and judgement. It may not be The Truth at all. 😢
A truth may only seem true when we look backwards, not forwards — i.e. in hindsight. iPhone will change phones forever is a truth now. But it was not in 2007. Many people predict futures wrong, even visionaries like Bill Gates and Steve Jobs.
Don't let your experience, knowledge and judgement limit your decision making, or you may completely miss it. Visionaries are visionaries because they learn and adapt their truths quickly. In hindsight, Steve Jobs got everything right. But don't look at the results. Look at the processes. Read his biography and you'll see how many times he was wrong — e.g. in 2008 Steve thought the App Store is a stupid idea. But he seemed get everything right eventually, because he knew his truth was not necessarily the truth. He adapted.
On the contrary, Steve Ballmer laughed at iPhone because he held his truth, that the software + service model is the way to go, not the tightly controlled software + hardware model. But in the case of mobile, it was completely wrong. It was not “the truth”. Unfortunately, Ballmer held his truth for a bit too long.
On the other hand, Google has tremendous success with Android, proving that Apple's software + hardware model is not the only truth out there, either.
The truth is always out there, but what's in your head, is just your truth.
