If you have an intense desire to do something then use that energy constructively to achieve your goal. When there is a strong desire, think of the options how to get it. At a logical level probably it might seem to be impossible, but still give it a focus attention assuming it is possible.
When desire is strong, feelings will be strong. It is entirely on you how you use this feeling - for achieving the goal or to regret about the impossibilities. If you are determined to give your best to what you want, you will definitely find some way out. Most of the people spend their energy on complaining or giving excuse why something cannot be done. This path will never take you to success.
Those who use their intense desire to search the path they need to take which can take them little closer towards their goal, make progress towards what they want. Such people when try hard, get what they desire for.
Use all your physical, mental and emotional energy to do what you want. Let the precious energy work for you. Do not let this get wasted in complaining and regretting.
If you have any intense desire, check all possibilities on the actions you can do to manifest it. Give it a try - your Best try. If it is your Best try then you will get what you want!
Cheers,
