Tip to become a successful software engineer.

To actually call yourself a software engineer you need to take into account a few aspects of what an engineer should do.

You’re Not Paid To Type

Typing code into a code editor or text editor is not what a Software Engineer is paid to do.  At least, it is not the primary reason this profession exists.  Yes, part of the job is to write code in any number of languages and platforms. As Derick pointed out, it is more then writing code, it is about writing tests, and making sure the code you do type works as designed and can be easily maintained.
All that being said, the actual act of typing is simple and quick.  There is training in keyboard typing and methods to increase how many words per minute one can type. So, does typing more code constructs per minute mean you should to get paid more money?  If you turn out more code then the engineer sitting next to you, have you created more value?  See where I am going with this.  Typing is easy, and typing the wrong code is really easy.  I have seen organizations that are fearful of missing deadlines and dates. Its so unhealthy that the developers think they need to start writing code NOW, but they don’t really know what they are supposed to be creating. They do know what to create in the general sense, but they rush into writing software without knowing most of the details.

You are paid to THINK, so start doing that

So, my main point of this post is that Software Engineers are paid to Think.  You are paid to think about what is the correct code to create, how is should be constructed to lower the total cost of ownership.
If you only change one thing about the way you work this year try this.

  If you normally get your requirements verbally, trying writing them down.

Write down your requirements or technical plan in the easiest manner possible. That could be on a whiteboard, you could annotate a screenshot of an existing screen, you could use pencil and draw the changes to a print out of a screen shot.  Just do something in terms of thinking about what needs to be done before you start typing.  If you do write down what you plan to do, you can actually communicate it to other developers. You can have someone else review it and think through the problem.  You can also show it to the person who will decide if you created the correct software, imagine getting some feedback on what you want to build before you mess it up?
The two most valuable ways I have found to write down what needs to be created are Screen Mockups and Sequence Diagrams. Now, I have been in the web space for a long time, so if you are not creating websites, or web applications, you may find that there are better ways to write down what you need for your particular design problem.  Either way , try to write it down. If you are writing mockups today, then add a sequence diagram for the more complicated problems and see if it helps.  I know it helps me and the developers I work with.
