I just moved home last month and like many other people, I started buying new furniture. One afternoon, I decided to assemble a chair for my study room. It seemed like an easy text to me - I have the skill, time, space, motivation, determination, and I totally have capability to assemble a simple chair, no doubt! My dad asked me, "You need a hand?" Of course I said no.
And what did I learn? Being confident was important, assessing the task's complexity was done, I had everything ready. What else? Oh... the tools, instructions and all the parts, they came with the package, all checked. Perfect!
So what did I miss? After spending half an hour putting the first two legs together by using this little tool, my hands were all red and tired. Does it look like a right tool to you? Now I get it, the tool, the RIGHT tool! Yes it was a right tool for this particular part of the chair, but it was not right for me. My dad asked me, "How's everything?" Of course I said good!
