Dreams.

Should we only believe in our dreams if they are reasonably attainable? Should we apply logic and then if the logic doesn't fit forgo the dream?  I say no.  All dreams that come true started out as a wish. Then ended as a dream come true because you put in the work to get there.

If you set yourself a goal you must also put in the work.  You must apply yourself, put your self in favor and remain focused.  You cannot afford many slips. But if you do, grow from them. If it's something you want to get better at, look at someone who you think is already the best at it. Do what they do. (and no it's not  copying, it's being smart and resourceful). Now watch someone who is bad at it, and avoid those pitfalls. Align yourself with the like-minded and steer clear from the absent-minded.

If you fail, you haven't tried hard enough.  DO OVER. Repeat if necessary.

Don't get discouraged and don't listen to the naysayers and the negative.

Remember that hard work begets great things. No work begets no things.

Truth be Told:  You dream. You believe. You activate. You plan. You work. You achieve.  You win.
