Define your goals and then make a plan to accomplish them.
Just know that, if your goals are worthy of achieving, this will not be easy.
There will be challenges and obstacles along the way.
Life will get in the way, but you will also get in your own way.
Do not underestimate your ability to distract yourself from the things that you claim matter the most to you.
Once you have established a goal or a set of goals you want to achieve, your internal resistance will begin to build.
You will begin finding excuses to not do the work necessary to achieve what you set out to accomplish.
Other, lesser goals will begin to entice you and pull you away from your primary purpose.
These distractions will come in many forms, some of which will feel extremely important, but deep down you will know that they are simply a means of avoiding the real work that will push you toward that which is most important to you.
The work that must be done to accomplish anything worthwhile is going to be difficult.
The difficulty of this work often pales in comparison, however, to the discipline required to avoid distractions and to stay on task.
You have already determined what your goals are.
Now get out of your own way.
