Yes, it is definitely a test of resourcefulness to persevere in the face of challenge, but you have to also know when you're doing the wrong thing or going down the right path. Persevering in the face of clear, direct evidence that what you are doing is not going to pan out is stubbornness. But persevering and LEARNING from what is working when other things are not is a best practice. The key is realizing when something is not working and then iterating to find the success. Or knowing that perhaps what you are doing will work, but the timing or market circumstances are not optimal, and then just biding your time until the market changes. This is not as obvious as one might think.
