For what time you have now set out to do and accomplish those things that you can now. Know what the vision is and write it down. Then break it all out in steps and focus on just one step at a time. You would find that if you really focus all of your energies on achieving that very first group of tasks in the first step, it all falls in place perfectly and your momentum would begin to increase. The more energy you build up in this way the more confident you begin to feel about your ability to achieve your set goals and in no time at all the vision would present itself to you as your reality.
If you plan to do too many things at a time you would only have for yourself a wavering mind and that is not so good when you are trying to achieve and succeed.
You need to train your focus. You brain needs to have a point of focus. Finish this one small thing and then move to the next.
Life is a dream with a series of dreams, so in fact you must keep on dreaming should you want to live at all.
Because passion is the soul of dream. Without which your dreams cannot become reality.
It is how life works.
If you cannot expand on a current dream any further for lack of enthusiasm and passion and you have the zest to birth a new dream then so be it.
