Following the dharma can either be hard or easy, it depends on the way you look at it. Also it depends on the way you apply it. If you believe that it is the way to be helped, to relieve your suffering, and help others, then it can be easier for you if you are motivated. On the other hand, it isn't called samsara for no reason. Samsara is like a pit with claws, once you are in, it is so so hard to come out. Sometimes it is the work that pushes people away, sometimes it is the people, but if you look deeper the only thing pushing you away is yourself.
It is very true what you said here jeremyg.....lets understand the reasons why people quits in the first place and then see what "antiniodes we can apply.
People quits because :
1) They lack the knowledge of how to do the job.
2) They know how to do it but the job takes too much of a challenge, time and effort.
3) They dont like to work with some people.
4) They dont like the job.
It all boils down to laziness and attachment to our comfort zone.
The antidodes could be a shift in how we think. This could start off with a bit of an ego trip, but in time, it will help us to elimanate our attachement to comfort zone and laziness. We dont quit and pursue the task even if we have to learn the skill and stay up late to accomplish it, we want to prove to the people who think we can't do it, wrong (yes, ego trip here)
When we succeed to do it, obviously we feel good and then we realise that actually we can basically do anything provided we dont "quit" in the first place. If what we accomplish is of a higher purpose, like helping or benefitting others, it will make us realise our individual potential is greater than what we think.
Humility should arise (lowering the ago)when we contemplate that if many of us do the same, then the potential and influence would be multiple.
In a spiritual context, we all know we should not quit, just bend and find other ways around the situation.
