It took me some time to realize the difference between a hot lead and a qualified lead or a waste of time. I have a software developer background and have picked sales and customer support roles in my hand. It helps me map customer pain and build a product.

In the noisy and glamorous world of unicorns and fundraising, solving customer pain and delighting them gets missed.
You have to pick your field and ace accordingly.
