Plan to learn on the job, or have it all sorted first?

[Scythe13]

This is an interesting question, because it covers so broad an area.

When it comes to skill sets that you think you'll need for the first year after 'the event', do you plan on learning as you go along, building on what you already know? Or do you plan to have all the basics down pat, so you know them well in advance.

As an example, learning to fix clothing is a great skill, but in the first year of post-event life, you'll probably not really need it. However, first aid is an important skill that you'll almost definitely need in the first year of life post SHTF.

How do you plan on these kinds of things?

Another example, planting and agriculture. Do you plan on 'learning on the job' or do you plan to have it all sorted before hand?

Please don't just focus on these few examples. The skills required are huge and varied, so expand your answer beyond the new examples I've provided.
