Guess the height

Guess the height

Imagine two pieces of railroad track of one km in length, laid end to end on ground. Each track has been nailed at the end and they join in middle.
Due to heat the tracks expand,each by 1 cm. The tracks are sturdy, remain straight but rise in the middle.
Guess by how many cms the tracks will rise ,in the middle, above the ground? No calculator please!

Deliberate practice improves our success in an interview

Practice is the act of carrying out an activity again and again, to gain mastery over an activity. Psychologist Professor Anders Ericsson coined the term deliberate practice. Talent is important but it is the deliberate practice which makes an ordinary man into extra-ordinary person.

Deliberate practice is purposeful and systematic. You need to have a specific goal, stay focussed, avoid distractions, follow a regular practice schedule, and step up the game in terms of tougher challenges, enable correct feedback to build and gain mastery. Breaking down a task and improving small chunks through regular practice with immediate and correct feedback helps hone the expertise. Deliberate practice is learning by doing and stepping into an uncomfortable zone.
