Manager's schedule:
  Traditional appointment book.
  Each day cut into one hour intervals.
  By default you've to change what you're doing each hour.

Maker's schedule:
  Prefer longer units of time, at least half a day.
  Can't work/switch every hour, barely enough time to get started.

On stressful days many of us give in to temptation and choose unhealthy options.

Six steps to avoid breaking unders stress

1. Acknowledge the tension, don't ignore it - we use self control every time we force ourself to make the good, reasonable decision, and that self control, like other human capacities is limited.

2. Call it what it is: ego depletion - depletion is the psychological sum of these feelings, of all the decisions you made that led to that moment.

3. Understand ego-depletion - people under greater cognitive strain were less able to overturn their instintive desires.

Your apps starts great and you love working with it up until beta when it becomes a mess and you hate it.

Your app is made up of things and know things about themselves and about others. The latter is dependencies. When the dependencies change, the object will need to change as well.

OO design makes you write code that your future self will love. Stop worrying and learn to love the mess.

  # Makes http requests.
  class Endpoint
    attr_reader :verb, :path, :provider, :endpoint, :access_token

    # TODO: remove config dependency,
    #       can combine path, endpoint, access_token
    #         depends on if OpenAuth can deal with full_url
    #       how to deal with provider?

When working through unknown code method, ask:

What does a given method do?
What is the current object context that I am in?
What other methods can I call here?

Recently I've been learning a lot about OOP, especially how to structure code to make it easier to change in the future. The following are some of the ways I refactored my open_auth2 library.

Don't optimize prematurely

I did the mistake of assuming what sugars were required, only to realize I never used them. Source.

Inject dependencies

The Token object accesses Config object for information. Before it was hard coded into Token, so they're highly coupled, so now I pass it as an argument to #initialize. Better yet it defaults to OpenAuth2::Config.new so it's only optional. Source.
