Only when there is a surplus can new things be created. Surplus means having more than what is necessary. Creating something new requires an initial investment in advance. Whether it’s labor or capital—that is, whether labor is purchased with capital—energy can only be used for new work if there is a surplus. Only with prior investment can something entirely new, never seen before, be made. The existence of something that did not exist before in this world results from someone putting in their surplus first. - Joseph’s “just my thoughts”
The advice to concentrate on one thing instead of trying to excel at many is valid, as it’s also challenging to master a single skill. If you neglect the other essential background abilities necessary to enhance that one skill, you will be unable to overcome your limitations. For a top-level skill to thrive, the supporting average abilities for that skill must also develop concurrently. Concentration should not be an excuse to avoid or ignore what’s important. - Joseph’s “just my thoughts”
