For many people, this is the only way to make money and feed their families. That's why we take it so seriously. Many have made fortunes on ICO projects.
This was during ICO days, but now it's rare that you will be fortunate to earn too much in bounty as the price pool is too small and it will be distributed into many applicants. It's good to still join as a extra job but taking it too seriously now can be just a waste of time since there is no guarantee that it will be paid after the projects succeed or will get the payment in time. It's long gone that bounties even you focus in too many projects will return a bigger amount after.
