Of what use is time if we do not have available resources to grow our businesses and bring every idea we have in our head into reality? Time is a very valuable asset, but no asset needed to grow a business or idea is more valuable than the other. A little decline in one can render every other effort useless. Time alone cannot bring ideas to life or grow a business. Imagine having all the time in the world but no knowledge on what exactly to do with the time. Money, knowledge, skills, people, tools are all important and there must be a balance between them all.
I think most entrepreneurs disregard it because it's not an asset that is being bought with money, they feel when you put in money into a business is what makes it grow
No serious minded entrepreneur disregards time even though they may not talk about it. Disregarding time leads to procrastination which hinders productivity. Moreover, time isn't the only valuable thing that is not bought with money. Some soft skills and talents may not be bought with money, but underestimating them is capable of slowing down growth.
