If you deeply aspire to achieve something, then by all means do all that is in your ability to achieve it, but remind yourself that you can do no more than just that. When you are already doing your best, you should not try to push yourself further, for it will not work, on the contrary, it will then only demotivate you. When you have reached the limits of your abilities, accept them as long as they are there, until you manage to push them further.
When you are already working hard to achieve your dreams, it is time to once more avert your focus from those dreams and turn it back on your experience. In this way, not only will it become more pleasant to work to achieve them, but you will also become better at it because you do so with more focus.
In this way, one can have very high goals without being pained by them. Whatever efforts you exert to achieve your goals, you must always do so step by step, departing from where you are to then arrive as close as you can get to your goal; if you have made up your mind what your goal is, it is no use of thinking about that goal when you are already doing everything to move closer towards it; instead, focus on how you move closer towards it and that alone. Devote yourself to what you do now, not to thinking of what you cannot do yet.

In the meantime, as you work to achieve your goals, enjoy what you have achieved so far and what you are achieving as you work. In this way, a compromise can be made between the need of achievement and a need of happiness without compromising either of both, and indeed actually improving both; similarly, such there are for all things.
