Easy to mistaken knowing with doing. “Sure I know how to do it” is different from” yes, I have done it.” Because knowing is not doing.
Having the knowledge is different than having the skills from actually done it. Because devil is in the details. Actual hands-on experience reveals nuances that would otherwise remain hidden. By working through the details is how one acquires the skill.
I learn this first hand from working on cars. Invariably, after I thought I knew how to do it, I get stuck on one tough piece that would not budge. The solution could be a tool, a part, or taking the car to a mechanic – either way a learning opportunity.
So, go ahead face the devil and tackle the details. It is the surest way to gain the experience and increase your credibility.
