Thought Habits

I believe habits are a major component for success of any kind.
And some habits are just a matter of how you think about things...

I realize that along the years I've been developing some thought habits - consciously or not.

For example, when I name files, I try to name them with the words for which I'll search for if I need to find this file in the future; many times I'll insert more than a single key-word, because my habit is to use the search capability of the OS. Another example is to pay attention to fallacies while considering someone else's arguments. There are others...

It becomes a habit when you trigger your mind to realize about those behaviours and apply them in the moment that you are thinking. By the way, a good book to understand habits: The Power of Habit, by Charles Duhigg.

One thought habit that I'm consciously currently trying to develop is focus. (I have a very divergent thinking, I'm very creative, and for that it's sometimes hard to me to converge and decide what to do)

Three techniques that I'm using and its inspirations:

1 - Once, I read a book about personal organization in which the main concept was "fix what's broken - only": make a list of the real problems that you are facing; things that are bothering you... then think why it happens; then find a solution... and then forget about trying to improve even more.

2 - MVP (Minimum Viable Product) is a concept strongly used in the start-up world. It means you should NOT try to build your final complete product, but rather to discover the minimum set of functionalities and requirements that bring some value, and try to prove your premisses before building your product. This will allow you to fix your original idea - because it's highly probable that it has some flaws. So, prototype solutions to learn more while incrementally building your final solution.

3 - The 80/20 rule. This is classic, but very few really use. It means to find the small subset of items / characteristics / functionalities (or whatever) that bring the biggest impact to your problem (or whatever). Usually there's only a small set of things with higher importance. Focus on the small set of things.

One example in which I'm trying to apply some focus habits: software development process.
We've been doing software for some time already... We tried many methods, tools and concepts, and with time we were able to identify some inefficiencies in our process.
So now we came with a set of "real problems for us" (not the problems of others, which say for example that you should use Scrum or whatever. We don't - it didn't work for us). For this set of problems we are able to identify some possible solutions, that we will have to test. But those are too many, and so we will focus only in some of them to begin with.

I tell you if it worked within some months...

Can you identify some good thought habits that you have yourself?
For the divergent thinking ones and creatives: how do you focus and converge and "pick one / some" when it's needed?
