The document discusses how to lead an efficient life by focusing on a specific area rather than trying to do everything. It recommends identifying a focus area by age 25, becoming efficient in that area by age 35, and achieving success by age 40 through dedicating over 24,000 hours of hard work. Being a generalist who knows many subjects but nothing deeply is seen as inefficient, while being an expert in one area but open to diversity is ideal. The key is becoming very efficient in a small domain through focused effort and teamwork.

1. We have only one life and we
want to do a lot of things in
this one life.
Can we do it all?
Should we do it all?

2. If you become efficient in
selected areas and forget
about doing all other
activities, you can use all your
resources efficiently.
You don’t need to be the one
and only expert. We need
thousands of experts in a
given market.
You must have ‘research and
development’ inside your
small box.

Up to class 12, you gradually come near to a specific area.
By the age of 22, you should make a decision on what you
want from life. Question is how big is your playground?
Do not do something at this age that nobody understands.

4. Your country’s economy, your market, your family, and you
must align in the efficient exercise. If everybody is going in
different ways, then there will be no efficiency.
Look at Bangladesh’s success in agricultural research.
Look at Bangladesh’s inefficiency in the film industry.

Knowing only one subject is full of short sightedness.
Knowing many subjects is full of inefficiency.
You need to be an expert but open to diversity.
Thus you need to be a team player.
But you cannot join many types of teams.

A smart Bangladeshi knows how to sing, draw, dance, play,
and have ten groups of friends in different areas.
An efficient Bangladeshi knows a lot about one subject area
and knows the key players in that area. We have thousands of
efficient people and we need millions more.

Identify your focus area by the age of 25.
Become efficient by the age of 35.
Achieve big successes by the age of 40.
That is 15 years x 200 days x 8 hours = 24000 hours of hard
work in one area.

Inefficient life means no focus at the age of 30+, random work
hours in different areas, efforts in industry that is impoverished
and inefficient in the country, improvisation of efficiency, very
loose connections in multiple teams, and no retirement plan.
You need to avoid this type of inefficient life.
