How flexible should we be with errors?

[yorkey181]

The further into this training I get, the more often I find what I'm looking at doesn't match what I see in the video. I'm now about 5+ hours in and I'm finding more and more that my results don't match or I get unexplained errors no matter how many tiems I check my code and settings.

Some of it seems to be related version numbers on solidity and I also wonder if there's issues because some of the testnet have changed/ no longer available? Even so, there's plenty of situations where I have the exact same code, all compiled OK, but I still get errors deploying or else different results when testing the deployed functions...

Currently on the Remix FundMe section on Fallback & Receive... only 5 lines of code, checked and double-checked several times, but still cannot get the results shown in the video?

So I my question is, should I stop and try to resolve every single issue, or just power on through and trust that it will all work itself out later on?

Appreciate any suggestions at all!
