A professor once told us to compare such a situation with climbing a mountain. You might be listening to someone who did this and tells you what it's like to look out into the country. And you believe without hesitation that that's a spectacular sight.
However, you have to start climbing yourself for real understanding what the view from the top is like.
And it's not that important to climb all the way to the top. It might be perfectly suficient just to reach a fair height above ground level.
But don't ever be afraid of start climbing. The view is always worth any efforts.
This has always been a nice analogy for me. I know this question was more about specific tips on how to efficiently deal with code bases once you started climbing. But nevertheless it instantly reminded me of our physics classes way back then.
