Our very nature seems to insist on emotional decisions; emotions want instant satisfaction. Once an emotional decision is made, it is hard to be rational and even consider changing our path. The time to seek rational thought is before a decision is made.
If an idea is in any way important - read a book and talk to successful people first. There are good general books on just about any subject; and while any breathing being will have an opinion, it is only those folks with success in what you are researching that can add value.
With more information under your belt it is time to invest thought and develop your own, flexible, ideas. The old fashioned way is to find a quiet spot with a nice view, take out a pad of paper and a pencil, and write down everything that pops into your mind - you can edit later.
Often what blocks constructive thought are problems that scream for attention; write those down as they appear and then forget them for now. You may even start a grocery list in a corner.
With your mind now somewhat clear of clutter start listing ideas about your current investment.
In a reasonable period of time you will create a short list of potential ideas. At any time come back and add a few, throw any shopping ideas back at that growing grocery list. You may reach a decision, but more likely you will find more information is needed. It's back to books, and successful people.
"Keep away from people who try to belittle your ambitions. Small people always do that, but the really great make you feel that you, too, can become great." - Mark Twain
It has been noted that most people will invest their life savings or start a career with less research than they use to buy a car. A "deal of the century" comes about every two weeks. If you miss this deal because you were learning and thinking, you will be better prepared for the next one.
Invest your thoughts first.
