Hard Work is Directly proportional to Results?

As we all know, I love physics and mathematics very much. That is, until I encounter a question I can't solve and wreck my brain finding a solution.

Work done= force x distance travelled in direction of force.
= lost in energy (potential, elastic, kinetic, heat, and so on)


Hence, we can conclude that;
More work is done when you put more effort(force) or When you travel a further distance in the direction of the force however No work is done if there is no distance travelled.

If you look at this in a more English-y way,
It requires more effort (hard work) to go further in (life?). However, it is useless if we keep working hard and not go anywhere, because all our efforts will be in vain. Therefore, we should not do something which requires a lot of effort but gives little in terms of results. That means that, even if you put in a lot of force(effort), it is almost the same as doing nothing(no work is done), because as "distance travelled in direction of motion tends to 0, amount of work done also tends to 0".

Based on the second equation,
The more work is done, the more energy is lost (converted to a different form)
Hard work requires a lot of energy. To get work done, energy must be lost in one form and increased in another. The principal of conservation of energy states that, "Energy can neither be created nor destroyed".

In a more literary way,
The more "physical" energy we lose, the more we gain in another area. For example, when we lose chemical energy(by working), we gain skills or knowledge (work done). The more work is done, the more energy is lost.

Where am I going? I don't know. I guess I'm just ranting.
