When estimates are made, then they are not just estimates,
it’s a way of ascertaining an uncertain future.

An uncertain future gets a glimpse of what seems to be possible in the present at the present moment in time when the estimate is being made.

Scope with regards to future varies in the present and also over a period of time along the future.
Each and everything comes into focus when an estimate is ready and needs to be followed in the present at the present moment in time.
Following a proper line of action comes later, much later.

Initially when everything related to making an estimate comes to mind it's important to take the right steps at the right moment in time.
.
Initially everything starts with particular line of thinking.
Initially in the present the thought process is very well defined,
so well defined that everything needs to be done keeping in mind the right moment in time.

Over a period of time things change and everything starts taking the right shape.
Now comes the moment in time to make an estimate since everything that is going on in mind gets sorted out and becomes clear.
Now the only thing that comes to mind is that time is going to be important.

Along with time comes an experience when efforts are been made
Along with experience comes accuracy in making an estimate
So never give up in life.

Give your best and always make efforts
A time will come when the importance of time will not only be understood, realized, agreed and accepted, but also it will be kept in mind.
An estimate will then be required keeping in mind the future.

So, there is nothing wrong in making an estimate
After all it takes only a small space of the entire page when making an estimate
So always see to it that you have your estimate ready for the plan that you have made in your mind and then only move towards taking the line of action.
