There are all kinds of different ways to get up hills.
Mountain goats seem to scamper up with nary a hitch in their stride.
Donkeys on the other hand take a more sure- footed plodding approach. It may take them awhile but they eventually get there. The same holds true for cyclists. You can decide to take the plodding approach or roar to the top with a vengeance. For a long steady climb you get to choose just how much pain you wish to endure and for how long.
